图2 不同光、氮条件下南方软米粳稻花后叶片中可溶性糖和淀粉含量的差异 处理同图1。图中所标注字母为叶片淀粉和可溶性糖含量的显著性, 不同字母表示在0.05概率水平差异显著。

Fig. 2 Differences in soluble sugar and starch content 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 in the content of soluble sugar and starch in leaves.
