Abstract

The influences of exogenously supplied gibberellic acid on amylase, catalase and carboxypeptidase B activities in cotyledons of germinating mung beans were studied. Gibberellic acid caused qualitative and quantitative changes in  α-amylase production. Cotyledons of seed germinated in the presence of GA3, developed more amylase activity than those germinated on water did. The present results indicated that GA3, induced two different forms [1 and 2] of α-amylase. The requirement of GA3, for the synthesis of α-amylase was also discussed. In contrast to amylase, catalase and carboxypeptidase B decreased during the time course of germination. No significant development of catalase and carboxypeptidase B activity was found in GA3,- treated cotyledons.
