Abstract
Glutamate dehydrogenase (GDH) activity, protein and total nitrogen contents in the secondary leaves of maize(Zea mays L. cv. Ganga Safed-2) seedlings increased during early seedling growth and then declined after reaching a peak level at either 10 d (GDH) or 12 d (metabolites). While the effect of kinetin on enzyme activity was statistically insignificant, benzyladenine supplied with nutrient solution increased GDH activity in secondary leaves of both 10-d as well as 14-d seedlings. However, both growth regulators increased the contents of total soluble proteins, total nitrogen, chlorophyll(a+b) and carotenoids in both 10 and 14-d old leaves.
