图3 孕穗期突变体及其野生型叶片的光合特性及叶绿体超微结构 A~D: 突变体及其野生型叶片的叶绿素a (A)、叶绿素b (B)、总叶绿素含量(C)及叶绿素a/b比值(D); E~H: 突变体(G, H)及其野生型(E, F)剑叶叶肉细胞超微结构, nu代表细胞核; Cl代表叶绿体; og代表嗜锇颗粒; I~J: 突变体及其野生型叶片的净光合速率(I)及Fv/Fm值(J)。1: 剑叶; 2: 倒二叶; 3: 倒三叶。* 表示在0.05水平上差异显著; ** 表示在0.01水平上差异显著(t-test)。

Fig. 3 Photosynthetic characteristics and chloroplast ultrastructure of leaves in the osdwl1 and wild-type plants at the booting stage A-D: Chl a (A), Chl b (B) and total Chl contents (C), and Chl a/b ratio (D) of leaves in osdwl1 and wild-type plants; E-H: ultrastructure of chloroplast in osdwl1 (G, H) and wild-type plants (E, F), nu means nucleus, Cl means chloroplast, og means osmiophilic granule; I, J: Net photosynthesis rate (I) and Fv/Fm ratio (J) of leaves in osdwl1 and wild-type plants. 1: flag leaves; 2: 2nd leaves from top; 3: 3rd leaves from top. Values marked with * and ** indicate significant differences by Student’s t-test at P < 0.05 and P < 0.01, respectively.
