摘要: 以珍汕97A、V20A、龙特浦A、博A为材料,通过暗室人工遮光处理,研究了它们的育性对光照长度的反应。试验结果表明,珍汕97A、V20A、博A在不同光照长度条件下,育性反应不同,龙特浦A的育性有明显反应,而且随着光照长度的增加,不育性愈好,呈幂函数关系。珍汕97A、V20A和博A没有明显的变化。

Abstract: The fertility response of cytoplasmic male sterile lines (CMS), Zhenshan 97A,V20A,Longtepu A, Bo A were studied under different light length conditions. The rate of dying pollen decreased as the light length increased in Longtepu A. There is a power function between the fertility of Longtepu A and light length. The fertility of Zhenshan 97A,V20A and Bo A almost showed no sensitiveness to the photoperiods.
