Kinetin and naphtaleneacetic acid controlled starch formation in isolated roots ofPisunt sativum

Abstract
The formation of starch in excised 3-days-old pea roots was enhanced up to three fold after cultivation for five days in liquid media containing 3% glucose, microelements, and 10-6 M kinetin or 10-7 M naphtaleneacetic acid (NAA). A synergistic effect of kinetin and NAA on starch formation was observed when both hormones were applied simultaneously over a wide range of concentrations.
