图1 ZH11与eed1成熟颖果表型分析 A: ZH11与eed1整粒成熟颖果外观比较, 标尺为1 mm; B: ZH11与eed1成熟颖果横切面比较, 标尺为1 mm; C: ZH11与eed1的成熟颖果大小比较, n = 20; D: ZH11与eed1的成熟烘干籽粒千粒重比较, n = 3。数值为平均值±标准差; 采用Student’s t测验, **表示P < 0.01; E~F: ZH11 (E)与eed1 (F)成熟颖果扫描电镜观察, 标尺为5 μm。

Fig. 1 Phenotypic analyses of mature caryopses of ZH11 and eed1 A: appearance comparison of the whole and mature caryopses between ZH11 and eed1, bar: 1 mm. B: cross-sections of ZH11 and eed1 mature caryopses, bar: 1 mm. C: comparison of mature caryopses size between ZH11 and eed1, n = 20. D: 1000-grain dry weight of ZH11 and eed1 mature grains, n = 3. Values are means ± SDs by Student’s t-test. **: P < 0.01. E-F: the scanning electron microscopic observation of mature caryopses of ZH11 (E) and eed1 (F), bar: 5 μm.
