| 摘 要： | 光敏核不育水稻（ＰＧＭＲ）营养生长期所遇光温条件，对后期育性转换的条件有一定影响。前期高温或短日条件，有使育性转换下限临界温度增高的作用；前期低温或长日条件，有使育性转换下限临界温度降低的影响。就此，作者讨论了各地所测的下限临界温度的相互参考价值。

| Abstract: | Conditions inducing the fertility alteration of photosensitive genic male sterile rice (PGMS) is the key point for the utilization of PGMS in hybrid rice production.The Photor-and thermo-conditions during vegetative growth phase can change the conditions inducing PGM$, fertility,alteration in the generative growth phase.High temperature and short-day conditious during vegetative growth phase can lower the critical Ptescribed minimum temperature of fertility alteration.Low. temperature and long-day , conditions during vegetstive growth phase of PGMS can decrease the critical prescribed minimum temperature of fertility alteration.As the photo-and thermo-conditions during vegetative growth phase of PGMS are various in different rice areas and seasons. the conditions .nducing fertility alteration are not constant. |
