图4 晋棉11与JBC4的iaaM基因转录水平、IAA含量、胚珠表面突起和成熟纤维数量比较 A: iaaM相对表达量; B: 开花当天胚珠中IAA激素含量; C: 开花当天胚珠表面纤维细胞突起数量; D: 棉花单粒种子成熟纤维数目。J11: 晋棉11; JBC4: 晋棉11与FBP7::iaaM回交4代纯合后代。采用Student's t- test检验分析数据; *和**分别表示在0.05和0.01水平上差异显著。

Fig. 4 Comparison of relative expression of iaaM gene, content of IAA, initial density in 0 DPA ovule and number of mature fibers in Jinmian 11 and JBC4 A: relative expression of iaaM gene; B: the content of IAA in 0 DPA ovule; C: the initial density of fiber in 0 DPA ovule; D: number of mature fibers per seed. J11: Jinmian 11; JBC4: the fourth generation of homozygous progenies of backcross. The significant difference was analyzed by Student’s t-test. * Significant at the 0.05 probability level. ** Significant at the 0.01 probability level.
