| 水稻品种的感光性强度与早、中、晚稻及其早、中、迟熟的趋势一致,二者有平行关系。155个代表性水稻品种的感光性强度,属中等的占多数,弱的其次,强的最少。同地区同熟期的粳稻感光性强于籼稻。还看到两种感光型。 |

| Abstract: |
| The parallel relationship between early,middle,Iate maturing type and the degree of photo-sensitivity in rice varieties was prese- nted.Geometrical progression which was based on 2 was presented in degree of photo-sensitivity in rice varieties.Most of the rice varieties belong to middle photo-sensitivity in 155 rice varieties, the second in number of iice varieties was weak,the faster in number of rice varieties was strong in photo-sensitivity.The photo- sensitivity of rice was stronger in Sinica than in In... |
