Abstract

Gibberellic acid (GA) is an important phyto-hormone mediating plant growth. In present study, we evaluated the impact of GA treatment on morphological, phenological and molecular aspects of five mungbean genotypes. GA treatment caused a significant increase in plant height and branch angle in most of the genotypes. However, there was no impact of GA treatment on days to first anthesis, days to 50% flowering and pod length. Genotypes SML-859 and EC-48 revealed no change in their plant height and branch angle respectively upon GA treatment, suggestive of their probable GA insensitivity. Expression of flowering associated gene- VrSOC1 remained unaffected by GA treatment, validating thereby that exogenously supplied GA does not induce early flowering in mungbeans.
