图4 不同光、氮条件下南方软米粳稻花后叶片中硝酸还原酶(NR)、谷氨酰胺合酶(GS)和谷氨酸合酶(GOGAT)的差异 处理同图1。图中所标注字母为硝酸还原酶、谷氨酰胺合酶和谷氨酸合酶的显著性, 不同字母表示在0.05概率水平差异显著。

Fig. 4 Differences of nitrate reductase (NR), glutamine synthetase (GS), and glutamate synthetase (GOGAT) activity in leaves after anthesis of southern soft japonica rice under different light and nitrogen conditions Treatments are the same as those given in Fig. 1. Different lowercase letters indicate significantly different at the 0.05 probability level for activity of nitrate reductase, glutamine synthetase, and glutamate synthetase.
