图1 野生型(WT)与突变体sol1的表型鉴定 A、B、C、D: 分别代表WT与sol1的五至六叶期、分蘖期、成熟期表型; E、F: 分别为WT与sol1未完全抽出时的叶基部; G: WT与sol1倒一叶近轴面基部; H: WT与sol1倒一叶远轴面叶尖; I: WT与sol1拔节期叶片卷曲指数; J: WT与sol1穗长及各节间长; K: 成熟期WT与sol1的各节间比较; L: WT与sol1拔节期叶夹角。图A、B、C、D、J中, Bar = 10 cm; 图E、F、G、H中, Bar = 2 cm。Top 1: 叶片顶端往下第一片叶; Top 2: 叶片顶端往下第二片叶; Top 3: 叶片顶端往下第三片叶。*: 在0.01 ≤ P < 0.05区间差异显著, **: P < 0.01差异极显著。

Fig. 1 Phenotypic identification of the wild type(WT) and the sol1 mutant A, B, C, D: plant phenotypes of WT and sol1 at the 5-6 leaf stage, the tillering stage and the mature stage, respectively; E and F: incompletely extracted leaf base of WT and sol1, respectively; G: bases of the abaxial top 1 of WT and sol1; H: tips of the adaxial top 1 of WT and sol1; I: leaf curl indexes of WT and sol1 at jointing stage; J: lengths of the spike and internodes of WT and sol1; K: comparison of the internodes of WT and sol1 at mature period; L: leaf angles of WT and sol1 at the shooting period. Bar = 10 cm, in A, B, C, D, J diagrams; Bar = 2 cm, in E, F, G, H diagrams. Top1: the 1st leaf from the top; Top2: the 2nd leaf from the top; Top3: the 3rd leaf from the top. * means significant difference at 0.01 ≤ P < 0.05 by t-test; ** means significant difference at P < 0.01 by t-test.
