Glutamine synthase (GS, a), glutamate synthase (GOGAT, b), NADH-dependent glutamate dehydrogenase (NADH-GDH, c), glutamic–oxalacetic transaminase (GOT, d), and glutamic–pyruvic transaminase (GPT, e) activities in different sucrose concentrations. Data refers to means ± SE (n = 4). Bars with the same letter are no statistically significantly difference at P < 0.05 by Duncan’s new multiple range method.
