Studies on seed quality attributes in shankapushpi (Clitorea ternatea L.)

Abstract

The experiment was conducted to study the effect of media, temperature, dormancy breaking treatments and biochemical changes associated with dormancy on seed quality of shankapushpi. The experiment results revealed that between paper method at 300C recorded highest germination (59.75%), seedling vigour Index-I (1277) and seedling vigour index-II (9700) in shankapushpi seeds. Among different dormancy breaking treatments, mechanical scarification (2side) recorded the highest seed germination (88.50%), seedling vigour Index-I (2423) and seedling vigour index-II (16583) respectively. With respect to different biochemical changes associated, highest α- Amylase activity (69.21 μg g-1) was recorded in the treatment mechanical scarification (2 sides). The banding pattern of esterase isozyme profile showed significant difference for different dormancy breaking treatments either by presence or absence of bands as well as intensity Their with Rm values ranged from 0.0158 to 0.0871.
