| 摘 要： | 应用生产上推广的6个陆地棉品种,以最后一次霜前花(10月10～25日)为样本,研究子指、百壳重、百仁重、种壳率、种仁率、仁/壳和发芽率这7个种子性状。结果表明:这7个性状在品种间存在着极显著差异,其中百仁重、种壳率、种仁率、仁/壳与发芽率之间存在着显著的相关和显著的直线回归关系。根据其回归关系,当种子棉的种仁率高于60.66%和仁/壳高于1.545时,发芽率才有可能达到80%以上。

| Abstract: | Seven seed traits of six upland cotton varieties were studied.The result indicated that significant difference existed among the varieties for seed index,hundred shell weight,hundred kernel weight,shell percentage,kernel percentage,kernel/shell and germination ratio.The correlation coefficient and the linear regression coefficient were significantly correlated between hundred kernel weight,shell percentage,kernel percentage and kernel/shell with the germination ratio.When the kernel percentage was over 60.6... |
