关于气候条件对植物育性的影响,国内外都有研究和报道。国内曾报道玉米一些不够稳定的雄性不育系,在早秋(日照较短)开花者,其雄性不育百分率较高于初夏(日照较长)开花者。表示日照长短对不育率的影响。国外曾报道水稻胞质雄性不育性的表现明显的受种植时间的影响。如1970年12月种植的(台中本地一号×潘克哈里)F_1植株的花粉不育率为93.6%,而同年四月种植的则为47.4%。另外,即使一般水稻品种,低温也能导致小花不育性。
On the climatic conditions on plant fertility, both at home and abroad have been studied and reported. Domestic maize has reported some not stable enough male sterile lines, in early autumn (shorter sunshine) flowering, male sterility percentage higher than in early summer (long sunshine) flowering. Said the effect of sunshine on the rate of infertility. Foreign countries have reported that the performance of cytoplasmic male sterility significantly affected by the planting time. The pollen sterility rate of F_1 plants grown in December 1970 (Taichung No. 1 Pankokhali) was 93.6% compared to 47.4% in April of the same year. In addition, even in general rice varieties, low temperature can lead to floret infertility.
