Influence of growth-promoting factors on activity of nitric metabolism enzymes in maize

The influence of growth stimulators «Appin-extra», «Vympel» and «Agat» on the activity of aminotransferases inthe seedlings of early-mid ripening hybrids of maize has been studied. It has been established that growth-stimulating processing causes the rise of aspartat aminotransferaseand alaninaminotransferase activities and accumulation of easily soluble proteins at the early stages of growth. Against the background of clear tendency of the aminotransferases activities increase under the influence of growth-promoting factors the cultivar-specific reactions have been revealed. It has been registered the existence of a correlation (r = 0.88–0.99) between enzymatic activity of aminotransferases and growth stimulation in the maize seedlings.
