Language: English Descriptors: Boron; Isotope labeling; Nutrient solutions; Nutritive value; Fruit; Flours; Vegetables; Wheat Abstract: Boron isotope ratios (11B/10B) for commercial produce ranged from a high of 4.162 +/- 0.003 for cabbage to a low of 4.013 +/- 0.008 for whole wheat flour. The observed isotope ratios for produce fall within the range reported for boron-containing minerals. Cucumbers and flour are 10B enriched; bananas, cabbage, celery, grapes, green peppers, lettuce, oranges, potatoes, and tomatoes are 11B enriched by at least 0.02; apples, broccoli, cantaloupe, and carrots are equal to NIST SRM-951 boric acid isotopic standard. Boron isotope ratios (11B/10B) were measured for broccoli and cabbage grown in a soilless medium, 4.018 +/- 0.016 and 4.032 +/- 0.003, in a soilless medium with foliar-applied H3 1OBO3, 1.848 +/- 0.009 and 1.746+/- 0.004, and in a hydroponic solution with H3 1OBO3 as the only boron source, 0.126 +/- 0.012 and 0.098 +/- 0.005. 19 NAL Call.

1991 May. Acta horticulturae (287): p. 207-210; 1991 May. Paper presented at the "Second International Symposium on Protected Cultivation of Vegetables in Mild Winter Climates," October 29-November 3, 1989, Crete, Greece. Includes references. Language: English Descriptors: Fragaria ananassa; Hydroponics; Boron; Requirements Abstract: Knowledge of the micronutrient requirements of strawberries is rather scarce. This plant species is considered to have low sensitivity to boron deficiency. In our work several aspects of B requirements of Fragaria ananassa L. cv. Douglas have been studied. Strawberries were grown in an automated greenhouse and in aerated nutrient solution with (+B) and with (-B) boron supply. The experiment started when fresh plants were transferred from the nursery to 4-litres pots (5 plants per pot) following the cultivation steps of a typical commercial production in Spain. Plant material (shoot and root) was sampled every two weeks after a gap of one month. Simulaneously, nutrient solutions were analyzed and renewed. B concentration in the n utrient solutions of both +B and -B increased during the 2-weeks period of culture. This increase was initially high but became smaller in successive periods. Boron content was higher in +B leaves than in -B ones. Nevertheless neither visula symptoms of B deficiency, nor reduction in growth in yield were observed in -B plants during the 4 months of the experiment. The lower boron concentration of young leaves in comparison with older ones would suggest a continuous supply of B from the root and a weak capacity of redistribution of the microelement via the phloem. In conclusion it appears that the large amount of boron stored mostly in the root at the beginning of the assay would be sufficient to cover the low B requirements of the strawberry plant studied. 20 NAL Call.

Language: English Descriptors: Lycopersicon esculentum; Nitrate; Potassium; Nutrient uptake; Ion uptake; Water uptake; Diurnal variation; Nutrient film techniques; Vegetative period Abstract: Tomato plants (Lycopersicon esculentum Mill.) of the F1 hybrid variety Turbo were grown in a NFT system for 22 days. On days 16 and 20-22 inclusive of the experiment, the diurnal variation in nitrate (NO3), potassium (K), and water uptake rates were measured. Nitrate and K uptake rates were subject to large diurnal variation with maximum uptake rates occurring during the day period. Two peaks of diurnal uptake rates were identified, one large peak during the day period and a second much smaller one during the first 2-4 hours of the night. Under the conditions of the experiment, night nutrition made up 35 to 40% of the total daily uptake of K and NO3. Water uptake rates followed a diurnal oscillation with a single peak pattern. Highest rates occurred at the middle of the photoperiod and lowest rates were measured at night. Over the entire day and night cycle there was no correlation between the rates of water and nutrient uptake. This may be of importance in the fertilization of hydroponically grown plants since in horticultural practice nutrients and water are supplied together in quantities large enough to meet plant water demand but not nutrient requirements. 49 NAL Call.

Language: English Descriptors: Lactuca sativa; Greenhouse culture; Growth; Hydroponics; Heating costs; Mathematical models; Temperature Abstract: An algorithm was developed to select a economically optimum temperature trajectory for greenhouse hydroponic lettuce production. Daily air temperature was selected to maximize he difference beween crop worth and cost to heat. To select an optimum temperature, crop worth was determined for a range of possible inside temperatures by projecting crop growth forward to harvest using expected values of weather variables based on historical weather data. After an optimum temperature for the day in question was selected, the status of the lettuce crop was updated based upon the selected temperature and the day's actual weather data. 53 NAL Call.

Language: English Descriptors: New York; Lactuca sativa; Crop production; Economic analysis; Greenhouse culture; Heating costs; Hydroponics; Simulation models; Temperature Abstract: Results of simulations from a computer model developed to determine economically optimum day temperature for greenhouse hydroponic lettuce production are presented. Selected optimum air temperature is a function of many factors including available insolation, stage of growth of the crop, length of the growing period, lettuce worth, and fuel costs. Potential savings due to production at optimum day temperatures compared to standard temperatures were estimated based on simulation of five years of operation. Potential savings vary depending on fuel cost and whether the greenhouse is operated such that only plants of the same age are present or such that many age groups are present simultaneously. Savings varied form 10 to 30% of the heating costs. 54 NAL Call. No.: 80 AC82 Effect of a mixture of organic subtances and iron on the growth and nutrient uptake of chrysantemum in NFT. Takano, T.

Paper presented at the "Symposium on Bedding and Pot Plant Culture," April 29-May 4, 1989, East Lansing, Michigan. Includes references. Language: English Descriptors: Dendranthema morifolium; Nutrient uptake; Organic compounds; Iron; Growth Abstract: In addition to essential inorganic nutrients, plants may need other organic substances as they have grown in soil. The capacity of microorganisms to synthesize biotic substances in a soil has been for a long time. Of these substances, a B-group of vitamins (Thiamine, Nicotinic acid, and Pyridoxine) and amino acid (cysteine) were selected as good source of nutrition for the plants. Present paper shows the effect of the addition of a mixture of these organic substances and iron to the nutrient solution on the growth and nutrient uptake in cut-flower chrysanthemum in the nutrient film technique system. A mixture of these substances added to the basal nutrient solution had a marked effect upon the growth and uptake of inorganic nutrients in chrysanthemum plant. Leaf green color was intensified by the treatment of liquid fertilizer containing thiamine, iron, and cysteine. As a side effect, these substances gave resistance of plants to unfavorable conditions. 55 NAL Call.

Language: English Descriptors: Lactuca sativa; Tipburn; Mineral deficiencies; Calcium ions; Nutrient solutions; Calcium nitrate; Nutrient film techniques; Hydroponics; Nutrient availability; Diurnal variation; Mineral content; Leaves Abstract: Butterhead lettuce (var. Gloria) were grown in an evaporatively cooled glasshouse using the nutrient film technique (NFT). During the day all plants received a complete nutrient solution (EC 2 dS/m). Treatments were imposed at night and included: complete nutrient solution (control); tap water (EC 0.19 dS/m); and calcium nitrate solutions containing either 100 mg Ca/L (EC 0.80 dS/m), or 200 mg Ca/L (EC 1.45 dS/m). Tipburn occurred in the control and its incidence was reduced by the other treatments. This effect was associated with an increase in the concentration of calcium in new leaves, except in the water treatment. The night treatments did not affect the fresh weight of mature lettuce. Circulation of either water or calcium nitrate (100 mg Ca/L) at night may, therefore, be a commercially acceptable means of reducing tipburn losses in lettuce crops grown using hydroponics. 62 NAL Call.

Language: English Descriptors: Vigna radiata; Fusarium solani f.sp. phaseoli; Roots; Infectivity; Regulation; Temperature; Hydrogen; Ion balance; Conidia; Spore germination; Inoculum density; Pathogenicity; Hydroponics; Growth Abstract: Hydroponically grown mung bean seedlings were inoculated with macroconidia of Fusarium solani f. sp. phaseoli to evaluate the effects of temperature (15, 20, 25, 30, and 35 C) and hydrogen ion concentration (pH 3, 4, 5, 6, and 7) on spore attachment to roots of Vigna radiata. Macroconidia of F. s. phaseoli attached to second-order roots

with root hairs in greater numbers than to those without root hairs or to roots of other orders. Attachment of macroconidia to second-order roots was greatest at 20-30 C and pH 4 but decreased by up to two orders of magnitude when the temperature of the nutrient solution was increased to 35 C or the pH elevated to 7. The binding reaction of macroconidia to roots was observed to be reversible when plants inoculated at 25 C and pH 5 were transferred to nutrient solutions maintained at 35 C or pH 7. Plant fresh weights of V. radiata decreased with increasing inoculum density when plants were inoculated and maintained at 20 or 25 C but not at 30 C. Differences in plant fresh weights of V. radiata between inoculated and uninoculated plants were greatest at 20 C, decreased at 25 C, and were not observed at 30 C. In a separate experiment, plant roots were exposed to inoculum for 24 h at 24 C and pH 4, 5, 6, or 7. The nutrient solutions of each treatment were then adjusted to and maintained at pH 6 for an additional 13 days. Disease was greatest when roots were inoculated at pH 4 as compared to pH 5 or 6. Plants inoculated at pH 7 were not different from uninoculated plants. Differences in disease among plants inoculated at different hydrogen ion concentrations are explicable when based on the effects of hydrogen ion concentration on the attachment of macroconidia to root surfaces. Differences in disease among plants inoculated at different temperatures between 20 and 30 C are not explicable when based on the effects of temperature on spore attachment to roots or on growth of the pathogen.

Language: English Descriptors: Ipomoea batatas; Genotypes; Screening; Adaptability; Hydroponics; Nutrient film techniques; Cultivars; Varietal reactions; Crop yield; Roots; Biomass production Abstract: Sweet potato [Ipomoea batatas (L.) Lam.] is among eight crops selected by NASA for its Controlled Ecological Life Support Systems (CELSS) program. This research evaluated sweet potato genotypes for adaptability to hydroponic systems. Fourteen sweet potato genotypes were grown hydroponically using nutrient film technique (NFT) systems. Four vine cuttings from each genotype were spaced at 25 cm and grown for 120 d using 14 NFT channels (0.15 by 0.15 by 1.2 m) supplied with a modified half-Hoagland nutrient solution. Genotypes responded differently to growth in NFT. 'Jewel' produced the highest mean total storage-root yield of 470 g per plant. Individual plant yields ranged from 767 g for 'Centennial' to 36 g for 'Bunch'. Inverse relationships between foliage weight and storage-root yield were obtained with 11 genotypes. Edible biomass indices were comparable to those of potato (Solanum tuberosum L.) and lettuce (Lactuca sativa L.), and higher than those of wheat (Triticum aestivum L.) and soybean [Glycine max (L.) Merr.]. Based on their performance, Jewel, 'Carver', TU-52, and Centennial sweet potato appear well adapted to growing in NFT. 81 NAL Call.

Paper presented at the "Workshop on Root Distribution, and Chemistry and Biology of the Root-Soil Interface", January 9-11, 1990, Ithaca, New York. Includes references. Language: English Descriptors: Lycopersicon esculentum; Hydroponics; Roots; Root systems; Containers; Volume; Growth; Stress; Biomass; Dry matter accumulation; Growth rate Abstract: We have developed a flow-through system (FTS) to

study the effects of root restriction stress on plants grown in hydroponic culture. The system was designed to permit the use of varied culture container volumes (from 25 to 1500 cm3) and dimensions (2.5 to 10 cm. dia. and 5 to 20 cm h.). The modular FTS design is divided into two nutrient delivery systems, one for large-volume containers and the other for small-volume containers. Each plant was grown in a modified Hoagland solution in a separate container. Nutrient solutions were aerated and the pH was automatically controlled at 6.0 +/- 0.2. This report describes the FTS and presents growth data for tomato plants (Lycopersicon esculentum Mill., cv. 'Better Bush') grown for a 57 day period. Our observations, when compared to the findings of a root restriction study made by Ruff, et al. 1987 (J. Amer. Soc. Hort. Sci. 112: 763-769), indicate that that similar characteristics result for the same tomato cultivar grown in either pot culture (soil) or hydroponics (FTS). The result of this test of the FTS supports the continued use of the system to study various physiological and hormonal parameters in relation to root restriction. 87 NAL Call.

Language: English Descriptors: Greece; Fragaria ananassa; Hydroponics; Greenhouse culture; Substrates Abstract: During the 1987-1988 and 1988-89 growing season an experiment was conducted in a cold plastic greenhouse of our Institute aiming to evaluate five substrates in two vertical systems with respect to their suitability for growing strawberries. The following substrates were evaluated: a. perlite 100%, b. perlite 90% + peat 10%, c. perlite 80% + peat 20%, d. pumice-stone 80% + peat 20%, e. pumice-stone 80% + perlite 20%. They were placed either in polyethylene tubes, 1.70 m height and 0.15 m diameter in a vartical position, or in pots of polystyrene placed one above the other in a column 1.70 m in height. In both cases, 36 plants of the strawberry cultivar Brighton were planted in each column in August. A system for recycling the nutrient solution was applied. Yield was collected from December until June. About 65% of the yield was taken until the end of April. Data obtained indicate that strawberries grown on substrate composed of perlite 80% + peat 20% produced higher yield (250 gr/plant) than those gorwn on the other substrates. There was no difference between polystyrene pots and polyethylene tubes with respect to yield. 108 NAL Call.

Language: English Descriptors: Scotland; Lycopersicon esculentum; Hydroponics; Perlite Abstract: The development of the hydroponic perlite culture system of protected crop production at the West of Scotland College has been based, hitherto, or coarse, 'horticultural- grade' expanded perlite which has 90% by volume in the range 1-5 mm. Recent work has compared crop performance of glasshouse tomatoes in horticultural-grade perlite with that in two Sardinian plaster-grades which have much finer particle-size distributions, one with 90% by volume in the range 0.6-1.4 mm, the other 90% volume < 1 mm. Cumulative yields of fruit were similar in each of the three grades of perlite to the end of Ausust in 1987 and to the end of September in 1988. Hence, although the air-filled porosity of the Sardinian plaster-grade perlite was lower than either the medium or horticultural-grade material, oxygen availability at the root surface did not limit root function. 124 NAL Call.

Language: English Descriptors: Artemisia annua; Medicinal plants; Plant composition; Molecular conformation; Sesquiterpenes; Lactones; Biosynthesis; Biochemical pathways; Immunoassay; Hydroponics Abstract: A highly specific and sensitive ELISA method was developed for the detection and semi-quantitative determination of artemisinin and its structurally related compounds in crude extracts of Artemisia annua. The antibodies were raised in rabbits using a 10-succinyldihydroartemisinin- BSA conjugate as immunogen. The peroxide linkage in the artemisinin molecule was critical in determining the antibody specificity. The working range of the assay was from 0.02 to 10 ng per assay. The cross-reacting material in crude plant extracts was evaluated by chromatographic methods combined with the immunoassay method. The distribution of artemisinin equivalents in five-week-old A. annua plants cultivated in hydroponic conditions was investigated. The highest artemisinin equivalent content (1.12% dry wt) was found in the leaves of the upper parts of the plant. 149 NAL Call.

Abstract: Dihaploid Solanum tuberosum and diploid S. microdontum plants were grown in soil and hydroponics under glasshouse and growth room conditions. A high light intensity, was necessary for flower induction in both species and the dihaploid flowered only when grown in hydroponics. Premature berry abscission was retarded by tuber removal and prevented by the addition of indole acetic acid to the nutrient solution. Seeds from prematurely abscised berries germinated poorly in soil, but germinated almost as well as those seeds from indole acetic acid-treated plants when placed on Murashige and Skoog (1962) based culture medium. The hybrid plants were intermediate in morphology, compared to the parents, possessed heterotic vigour and were male fertile. Germinating hybrid seeds on a colchicine-containing medium led to poorly growing plants with ploidy chimeras. Hybrid plant ploidy levels were doubled by regenerating plants from stem/leaf explants on the tuber disc regeneration medium of Jarret et al. (1980). 150 NAL Call.

Language: English Descriptors: Gleditsia triacanthos; Roots; Plant morphology; Root hydraulic conductivity; Hydroponics; Root systems; Length Abstract: The morphology and hydraulic conductivity of root systems of Gleditsia triacanthos L. var. inermis Willd. (honey locust) grown hydroponically in sand and solution cultures were compared. Total root system length was similar in the two cultures. However, root systems grown in solution had longer primary roots, fewer lateral roots and root hairs, and a greater distance between the tip of the primary root and the junction of the youngest secondary root and the primary root than root systems grown in sand. Hydraulic conductivities of

root systems grown hydroponically for 21 or 35 days in sand or solution culture were similar. These findings show that different methods of hydroponic culture can affect root morphology without altering root resistance to water transport. 157 NAL Call.

Language: English Descriptors: England; Lycopersicon esculentum; Nutrient film techniques; Yield response functions Abstract: It is possible to restrict the vegetative growth of early protected tomato crops, growing in the nutrient film technique (NFT) water culture, by supplying the nutrient solution intermittently instead of continuous flow. Intermittent flow regime given up to anthesis of the fourth truss, increased early yield but did not increase the final total yield. There was a highly significant decrease in root fresh weight. Also, a reduction in all intermittent treatment of water consumption 22%, was noticed under the intermittent flow. The water use efficiency calculated on the basis of fresh and dry weights increased under intermittent treatments. 168 NAL Call.

Lam] is being grown with the nutrient film technique as part of the National Aeronautics and Space Administration's Controlled Ecological Life Support System (CELSS) program for long-termed manned space missions. Our objective was to evaluate the effects of two levels of photosynthetic photon flux (480 and 960 micromoles m(-2)s(-1) PPF) and three N/K ratios (1:1.1, 1:2.4, and 1:3.6) on yield of sweetpotato when grown using this technique. Vine cuttings (15-cm length) of 'Georgia Jet' and T1-155 were grown in each treatment for 90 or 120 d, respectively, in controlled-environment growth chambers. Storage root growth for Georgia Jet and T1-155 increased with light intensity, while foliage growth decreased with high K levels. The number of storage roots produced by each plant increased with intensity only for Georgia Jet but was not significantly influenced by higher K levels for either cultivar. Light by N/K interactions were not significant. The level of PPF exerted a greater effect in enhancing sweetpotato storage root yield in nutrient film than did N/K ratio. 169 NAL Call.

Rockville, Md. : American Society of Plant Physiologists; 1991 Apr. Plant physiology v. 95 (4): p. 1125-1130; 1991 Apr. Includes references. Language: English Descriptors: Plant nutrition; Laboratory equipment; Hydroponics; Nutrient uptake; Nutrient solutions Abstract: We describe the mechanical, electronic, hydraulic, and structural design of a nonrecirculating hydroponic system. The system is particularly suited to studies at very low nutrient concentrations, for which on-line concentration monitoring methods either do not exist or are costly and limited to monitoring relatively few individual plants. Solutions are mixed automatically to chosen concentrations, which can be set differently for every pump fed from a master supply of deionized water and nutrient concentrates. Pumping rates can be varied over a 50-fold range, up to 400 liters per day, which suffices to maintain a number of large, post- seedling plants in rapid growth at (sub)micromolar levels of N and P. The outflow of each pump is divided among as many as 12 separate root chambers. In each chamber one may monitor uptake by individual plant roots or segments thereof, by measuring nutrient depletion in batch samples of solution. The system is constructed from nontoxic materials that do not adsorb nutrient ions; no transient shifts of nitrate and phosphate concentrations are observable at the submicromolar level. Nonrecirculation of solutions limits problems of pH shifts, microbial contamination, and cumulative imbalances in unmonitored nutrients. We note several disadvantages, principally related to high consumption of deionized water and solutes. The reciprocating pumps can be constructed inexpensively, particularly by the researcher. We also report previously unattainable control of passive temperature rise of chambers exposed to full sunlight, by use of white epoxy paint. 196 NAL Call.

Language: English Descriptors: Lycopersicon esculentum; Molybdenum; Nutrient uptake; Ion uptake; Nutrient nutrient interactions; Phosphorus; Mineral deficiencies; Nutrient film techniques; Ph; Nutrient transport; Plasma; Membranes; Roots; Radionuclides; Dry matter accumulation; Mineral content; Shoots Abstract: Water culture experiments are described which provide conclusive evidence that Mo uptake by tomato plants is markedly enhanced by P deficiency. In a longterm experiment, which ran for 11 days, in marked contrast to the uptake of other nutrients, a three fold higher Mo uptake rate was observed after only four days of withdrawal of P from the nutrient medium. In contrast to the gradual increase in pH of the nutrient medium of the plants supplied with P, the pH in the medium of the -P plants fell. Throughout the growth of these plants net H+ efflux could be accounted for by excess cation over anion uptake, indicating that organic acid extrusion plays no major role in the observed fall in pH. Further evidence that Mo uptake is enhanced in P deficient tomato plants is provided in short-term nutrient solution experiments (1h and 4h) using radioactive molybdenum (99Mo). Compared with P sufficient plants, the uptake rates of 99Mo by P deficient plants were three to five times higher after 1h and nine to twelve times higher after 4h. Resupplying P during the uptake periods to deficient plants reduced the uptake rate of 99Mo to values similar to those of P sufficient plants. It is concluded that the uptake of molybdate occurs via phosphate binding/ transporting sites at the plasma membrane of root cells. Further support for this conclusion comes from exchange experiments with non-labelled molybdenum, which show a much larger amount of 99Mo exchangeable from the roots of P deficient plants. 206 NAL Call.

Potato plants were grown for 42 days in sloping shallow trays containing a 1 cm layer of quartz gravel with a continuous flow of 4 ml min(-1) of nutrient solutions having K concentrations of 0.10, 0.55, 1.59, 3.16, 6.44, 9.77 meq L(-1). Plant leaf area, total and tuber dry weights were reduced over 25% at 0.10 meq L(-1) of K and over 17% at 9.77 meq L(-1) of K compared to concentrations of 0.55, 1.59, 3.16 and 6.44 meq L(-1) of K. Gas exchange measurements on leaflets in situ after 39 days of growth demonstrated no significant differences among different K treatments in CO2 assimilation rate, stomatal conductance, intercellular CO2 concentration, and transpiration. Further measurements made only on plants grown at 0.10, 1.59, 6.44 meq L(-1) of K showed similar responses of CO2 assimilation rate to different intercellular CO2 concentrations. This suggested that the photosynthetic systems were not affected by different K nutrition. The leaves of plants accumulated about 60% less K at 0.10 meq L(-1) of K than at higher K concentrations. However, Ca and Mg levels in the leaves were higher at 0.10 meq L(-1) of K than at higher K concentrations. This indicates that low K nutrition not only reduced plant growth, but also affected nutrient balance between major cations. 216 NAL Call.

Language: English Descriptors: Lycopersicon esculentum; Nutrient solutions; Hydroponics; Nutrient availability; Cation exchange resins; Cation exchange; Metal ions; Nickel; Chelation Abstract: A recirculating resin-buffered hydroponic system was developed to control the activities of nutrient ions in solution at concentrations similar to those found in soil solution. The recirculating hydroponic system was designed to supply adequate buffering and timely replenishment of nutrients during the course of long-term experiments. Nutrient solution was recharged by circulating it through columns of ion exchange and chelating resins before its return to plant culture vessels. The recirculating resin-buffered system consisted of four different types of ion exchange and chelating resins housed in separate columns: strong-acid resin to buffer Ca, Mg, K and Mn in solution; weak-acid resin to buffer pH; partially-neutralized Al on strong-acid resin to buffer P in solution; and chelating resin to buffer Zn, Cu, Mn, and Ni and to supply Fe to EDDHA in solution. Control of nutrients and pH was begun at the time of seed germination. The recirculating resin-buffered system was especially designed to limit Ni contamination in studies of the essentiality of Ni in higher plants. Concentrations of Ni2+ is solution were successfully maintained at treatment levels that differed by four orders of magnitude, with the lowest level < 10(-14) M. The exchange resins maintained the supply and activities of other nutrients at levels sufficient for the

growth of plants. Tomato plants (Lycopersicon esculentum Mill., cv. Wisconsin 55) were successfully grown for six weeks without discarding the nutrient solution in which the plants grew. The pH of recirculating nutrient solutions was well maintained throughout the study. Guard columns protected the primary resin columns from plugging and were replaced during the course of this study to restore flow rates of the nutrient solutions. Maintenance of flow rates, in conjunction with successful reloading of resins with nutrients, assures the feasibility of even longer term plant culture experiments. 226 NAL Call.

Language: English Descriptors: Triticum aestivum; Genotypes; Hydroponics; Greenhouse culture; Soil water content; Soil water regimes; Root systems; Shoots; Growth rate; Drought resistance; Flooding tolerance; Varietal reactions Abstract: Root characteristics of wheat (Triticum aestivum L.) genotypes are believed to be important in tolerance to drought and flooding, yet neither the extent of differences in root size among modern soft red wheat cultivars nor the degree of association between root size and drought or flooding tolerance is known. This study was conducted to see whether genotypes differ in root size, and to see if root size is associated with tolerance to flooded soil and to drought during early vegetative growth. We found differences in root fresh weight (RFW), shoot fresh weight (SFW), number of roots longer than 40 cm (NR), longest root length (LRL) and total root length (TRL) of 40 winter wheat genotypes grown in hydroponic culture for 4 wk. Each of these parameters was positively correlated with all others. Twelve genotypes with different root sizes selected from these 40 were grown in a greenhouse soil experiment for 3 wk, after which soil moisture treatments of control, flooding, and drought were imposed for a period of 21 d. Flooding did not affect SFW and number of tillers (NT), but decreased RFW. Drought drastically decreased all three parameters. The genotype X moisture treatment interactions for SFW, RFW, and NT were significant. Root and shoot growth of these genotypes in hydroponic culture were correlated to their root and shoot growth under both control and flooded conditions, but not under drought. Thus, it appears that the expression of genotypic root growth potential may be influenced by the availability of soil moisture, and

that selection of wheat seedlings for vigorous growth in hydroponic culture will select for vigorous early growth in soil with adequate or excess moisture, but not under severe drought. 236 NAL Call.

The hydroponic culture screening method was more severe than the sand culture method. Common bean cultivars/lines expressed genetic variability to salinity stress at thirty-eight-days old seedlings. 'Badrieh' was tolerant to salinity as the tolerant tepary bean T#1 line under sand culture. However, this was not evident under hydroponic culture. T#1 showed salinity injury symptoms at EC = 4 dS/m, while 'Badrieh' showed no salinity injury symptoms at EC = 4 dS/m. These results indicate that the mechanisms involved for tolerating salinity in the tepary could be different from that involved in common beans. Inverse and significant correlations between salinity injury symptoms and several root and shoot characters were evident from the data, indicating that variation in whole-plant foliar injury symptoms to salinity would thus seem to provide the best means of initial selection of salinity tolerant genotypes by plant breeders. 242 NAL Call.

Language: English Descriptors: Lycopersicon esculentum; Crop quality; Crop yield; Greenhouse culture; Hydroponics; Malic acid; Plant water relations; Salt tolerance Abstract: Commercial recommendations exist for using short- term salt-shocks on tomato (Lycopersicon esculentum Mill.) to improve fruit quality. Six experiments were conducted to 1) assess the influence of nutrient concentration and short-term salt-shocks on fruit quality and yield and 2) identify a vegetative predictor of subsequent fruit quality. The first objective was addressed in three nutrient film technique (NFT) experiments (Expts. 1-3). Four treatments were applied: two maintained constant at two baseline concentrations (0.25X and 1X-commercial level) and two provided salt-shock periods of 30 min, twice daily. There were no effects of baseline concentration or salt-shocks on total number and weight of marketable fruit. Fruit quality was better at the 1X baseline concentration as observed by higher titratable acidity (Expt. 2), higher percent dry matter (Expts. 2 and 3), higher soluble solids concentration (Expt. 2), and lower pH (Expts. 2 and 3), however, weight per marketable fruit was lower (Expt. 2). Salt-shocks had little effect on fruit quality, refuting its commercial potential. Salt-shocks decreased fruit pH (Expts. 1 and 3). However, titratable acidity increased at the 0.25X level and decreased at the 1X level (Expt. 3). In Expt. 2, but not in Expt. 3, citrate concentration in the fifth leaf from the apex of young vegetative plants was correlated with subsequent fruit quality. Three additional experiments in static hydroponics with vegetative plants showed no significant differences in leaf citrate levels due to a single, short-term salt-shock. Thus, citrate is not a good predictor of fruit quality. 247 NAL Call. No.: 80 C733 Soilless growing in Europe (Vegetables, hydroponics, England, Poland). Schippers, P.A. Willoughby, Oh.

Journal of the American Society for Horticultural Science v. 114 (6): p. 890-893. ill; 1989 Nov. Includes references. Language: English Descriptors: Cucumis sativus; Hydroponics; Circulation; Nutrient solutions; Depth; Growth rate; Roots; Shoots; Morphology Abstract: Defruited cucumber (Cucumis sativus L.) plants were grown hydroponically for 28 days in containers with 4.5 liters of capacity, in which constant solution depths of 1, 5, 50, and 170 mm were maintained. The plants grown in the 1- and 5- mm-deep solutions grew more slowly than those in the deeper solutions. Both root and shoot growth were reduced at the shallow depths, but shoot growth was affected more than root growth. Thus, the shoot : root ratios were considerably smaller in the shallower than in the deeper solutions. The root systems in the shallower solutions, initially, were relatively more branched than in the deeper solutions. The shallow solutions caused the plants to allocate a higher proportion of their photosynthetic resources to the root at the expense of leaf growth. In the shallow solutions, a progressively higher proportion of this root growth became exposed above the solution, and, therefore, could not contribute to the absorption of water and nutrients. Control of solution depth may be a useful tool for controlling the vigor of the shoots of cucumber and the data presented may explain why growth problems have been experienced with this crop, particularly where a very thin film of nutrient is used, as in nutrient film technique.

Language: English Descriptors: Lycopersicon esculentum; Plant parasitic nematodes; Laboratory rearing; Meloidogyne javanica; Nematode juveniles; Hydroponics; Nutrient solutions; Culture techniques; Host range; Pathogenicity Abstract: A hydroponic culture system that enables ready production and retrieval of freshly hatched, infective root- knot nematode juveniles was developed. Meloidogyne javanica- infected tomato plants produced at least 100,000 juveniles per day for as long as 3 mo. Juveniles reinfected roots within the culture system, which possibly accounts for the extended period of production. The hydroponically grown nematodes retained characteristic infectivity and host range. This culture system is useful when a cohort of uniform-age juveniles is required or for analyses in which high numbers of nematodes are needed. 266 NAL Call.

Language: English Descriptors: Lolium perenne; Tillering; Leaves; Growth; Hydroponics; Water potential; Cultivars; Genetic variation; Mathematical models; Equations Abstract: Tillering and growth parameters of perennial ryegrass cultivars Wendy (diploid) and Condesa (tetraploid) were determined in a glasshouse experiment using hydroponics at low (-1.3 MPa) and normal water potential (0 MPa). At -1.3 MPa, leaf extension rate was reduced by 36%. Final plant tiller number was 20% lower at -1.3 MPa because of a 12% reduction in the leaf appearance rate in the first weeks after the start of the treatments. Site filling, the relative increase in tiller number per leaf appearance interval, was high (0.61) - but still lower than theoretically possible - and was only slightly affected by water potential. Site filling was shown to be strictly related to the number of inhibited plus unemerged tiller buds. Dry matter production was 64% lower at -1.3 MPa. Relative growth rate (RGR) was, on average, 17% lower at -1.3 MPa, but the reduction was greater just after the treatments started. Also, net assimilation rate (NAR) was reduced more by low water potential just after the start of the treatments. Specific leaf area (SLA) was 13% lower at -1.3 MPa for Wendy, but not significantly reduced for Condesa. Contrary to expectations based on the theory of the functional balance between root and shoot, leaf weight ratio was slightly higher at -1.3 MPa. From comparison of the results of this study with published data, it is concluded that effects of drought in the field on tillering cannot be attributed only to low water potential. 270 NAL Call.

Language: English Descriptors: Lactuca sativa; Brassica chinensis; Ipomoea aquatica; Roots; Urea; Nitrogen metabolism; Urease; Enzyme activity; Nutrient solutions; Ph; Hydroponics; Nitrate Abstract: Substitution of urea for commonly used nitrate fertilizers in hydroponic culture of vegetables would not only avoid excessive accumulation of nitrate in plants but would also reduce the cost of production. This substitution,

however, might have adverse effects, such as a dramatic decrease in solution pH, reduced nutrient uptake and possibly urea toxicity per se. Differences in adaptability to urea were found among three species of leafy vegetables, Ipomoea aquatica Fossk., Lactuca sativa L. and Brassica chinensis L. I. aquatica showed the best adaptability, growing normally with urea as the sole nitrogen source in spite of the dramatic pH decrease in the nutrient solution. It was further found that I. aquatica had significantly lower urease activity in the roots than the other two species when urea was supplied to the solution. Tolerance of low pH and avoidance of urea toxicity may be possible mechanisms of I. aquatica's adaptability to urea application in hydroponic culture. 280 NAL Call.

Alexandria, Va. : The American Society for Horticultural Science; 1992 Nov. HortScience : a publication of the American Society for Horticultural Science v. 27 (11): p. 1183-1185; 1992 Nov. Includes references. Language: English Descriptors: Phaseolus vulgaris; Hydroponics; Gravity; Nutrient solutions; Distribution; Systems; Vacuum tanks; Growth; Responses; Crop production Abstract: A nutrient delivery system that may have applicability for growing plants in microgravity is described. The Vacuum-Operated Nutrient Delivery System (VONDS) draws nutrient solution across roots that are under a partial vacuum at approximately 91 kPa. Bean (Phaseolus vulgaris L. cv. Blue Lake 274) plants grown on the VONDS had consistently greater leaf area and higher root, stem, leaf, and pod dry weights than plants grown under nonvacuum control conditions. This study demonstrates the potential applicability of the VONDS for growing plants in microgravity for space biology experimentation and/or crop production. 286 NAL Call.
