摘要
经两年光敏核不育谷子光周期诱导研究表明:1.长于14h日照长度诱导雄性不育,短于13h日照长度诱导可育。2.幼穗生长锥伸长期至雌雄蕊分化期为光敏核不育谷子育性转换敏感期。3.光敏核不育谷子存在着两个性质不同的光周期反应。
The research on the induction of photoperiod-sensitive nuclear genetic male sterile foxtail millet by sunshine had been conducted for two years. The results were as follows. 1. Male sterile was induced when sunshine time was longer than 14 hours, but as sunshine time was shouter than 13 hours, male fertile was brought out. 2. To the millet, the sensitive stage during which male fertility and sterility would be converted into each other was from the stage of growing tip lengthening to the stage of stamen and pistil differentiation. 3. There were two sorts of response for photoperiod sensitive nuclear genetic male sterile foxtail millet to sunshine.
