图4 野生型和突变体nal20叶片细胞大小和数目 A, B: 野生型(A)和突变体nal20 (B)成熟期剑叶下表皮细胞形态, 标尺为50 μm; C, D: 野生型和突变体nal20抽穗期的叶片下表皮细胞大小和细胞数目的比较。t测验计算P值, **表示突变体在P < 0.01水平差异显著(n = 20)。

Fig. 4 Epidermal cell width and cell number of wild type (WT) and the nal20 mutant A, B: Epidermal cell shape of flag leaf in the wild-type (A) and mutant (B) (bars = 50 μm); C, D: comparison of epidermal cell width and cell number along leaf-width axis. P-values were analyzed from Student’s t-tests. ** P < 0.01 (n = 20).
