• Some authors have described the ABA action on water-plant
relationships (Hose et al., 2000; Thompson et al. 2007) through
aquaporins
• When aquaporins channels are opened, cell to cell water pathway
increases and root hydraulic conductivity (Lpr) is enhanced
• As consequence a higher movement of water and nutrients is observed
from root to shoot
![Page 36: Roberto 1Baigorri & José M García-Mina - Acefer · Baigorri et al., J. Phys Chem B., 2007 .

Experiment with HA measuring Lpr, ABA and aquoporins was carried out in
order to explore the hypothetical HA action through ABA.
This experiment was completed using Fluridone (Fld) a ABA synthesis inhibitor
