INDUKSI KALUS EMBRIOGENIK PADA PERBANYAKAN LEEK (Allium porrum L.)EMBRYOGENIC CALLUS INDUCTION ON THE MULTIPLICATION OF LEEK
(Allium porrum L.)
ABSTRACT
Multiplication of leek (Allium porrum L.) by tissue culture is an alternative to the provision ofseedlings, especially if the varieties no tillering and not able to flowering during plant productionin Indonesia. A study was conducted to determine the best various of explant and growth regulatorcomposition to induce embryogenic callus. Primary somatic embryos obtained by planted explantleaf base and root tip on MS medium containing 2.4 D and BA. At a later stage, primary somaticembryos will form a secondary somatic embryo after subculture. 1 month old root tips are the bestexplants for induce embryogenic callus, while ZPT 1.0 mg / l 2.4 D + 1.0 mg / l BA was the mostappropriate composition to induce embryogenic callus.
