The effect of GA and CCC on the physiology of the developing first leaf of pigeonpea was studied. Gibberellic acid, and the higher concentration (1,000 ppm) of CCC reduced the levels of protein synthesis and, consequently the dry weight. Lower proteinase activity was evident in the GA-treated leaves during early stages of leaf development and expansion of the lamina which could be correlated with high levels of protein and chlorophyll. The disc electrophoretic protein profiles showed a clear-cut developmental pattern, with the age of the leaf.
