| 摘 要： | 本研究以BNS小麦为试材,采用分期播种和春季播种试验,研究BNS不同播期的幼穗分化进程及其温光与育性的关系,旨在进一步明确BNS育性转化的穗分化敏感时期.结果表明:(1)随播期推迟,BNS二棱期至药隔期的穗分化天数和不育度均逐渐减小,且二者呈极显著正相关(r=0.940～0.942>r(0.05/0.01)=0.658...

| Abstract: | In order to further clarify the fertility alteration period of BNS, the spike differentiation process and the relationship between temperature light and sterility were studied by the means of time sowing in autumn and spring. The result showed that: (1) Along with the sowing time delay, both of the differentiation days from double ridge period to anther separation stage and sterility degree decreased gradually. The correlation was extremely significant between the differentiation days and the sterile degree... |
