图3 野生型和突变体nal20叶脉数目比较 A, C, E: 野生型剑叶、倒二叶和倒三叶的叶脉, 标尺为1 mm; B, D, F: 突变体剑叶、倒二叶和倒三叶的叶脉, 标尺为1 mm; 图中*表示大叶脉, 2个大叶脉中的圆点表示小叶脉; G, H: 野生型和突变体大叶脉数目(G)和小叶脉数目(H)的比较。t测验计算P值, 柱形图中**表示突变体在P < 0.01水平差异显著(n = 20)。

Fig. 3 Leaf vein number of wild type (WT) and the nal20 mutant A, C, E: leaf vein shape of the flag leaf, top second leaf and top third leaf in the wild type (bars = 1 mm); B, D, F: leaf vein of the flag leaf, top second leaf and top third leaf in the mutant (bars = 1 mm); G: comparison of large vein number in the wild type and mutant; H: comparison of small vein number in the wild type and mutant. P-values were analyzed using Student’s t-tests. ** P < 0.01 (n = 20).
