图2 野生型和突变体nal20的叶片长度 A: 野生型(左)和突变体nal20 (右)抽穗期的剑叶形态比较, 标尺为5 cm; B: 剑叶、倒二叶和倒三叶叶片长度比较。t测验计算P值, 柱形图中 *表示突变体在P <0.05水平差异显著; **表示突变体在P < 0.01水平差异显著(n = 20)。

Fig. 2 Leaf length of wild type (WT) and the nal20 mutant A: top leaf size of wild type and the nal20 mutant at heading stage (bar = 5 cm); B: length comparison of flag, second, and top third leaves between WT and nal20. P-values were analyzed using Student’s t-tests. * P < 0.05, ** P < 0.01 (n = 20).
