Abstract:
Six varieties including Heinong 35,Dongnong 42,Dongnong 46,Kenfeng 9,G.gracilis and G. soja were tested by means of pots experiments to study the dynamics of NADH GOGAT activities in different genotypes soybean.The results indicated that during the whole growth stage,the dynamics of NADH GOGAT activities in the leaves presented a drop rise drop tendency in G.gracilis and G.soja,the other varieties had a single-peak curve;in stems it showed a single peak curve;activities in roots of the tested varieties except Heinong 35 and Dongnong 42 showed a single-peak curve;in the nodules of Dongnong 46 appeared a double peak curve,but the other varieties had a single peak curve;in pod decreased gradually with development.The gradation of GOGAT activities in different organs was leaf>nodules>stem>root>pod shed.The NADH GOGAT activities in leaves and stems were significant positively correlated with the protein content in seeds at R4.
