| 摘要: |
| 设计了三种温度和四种日长共12种光温互作处理对21个不同类型的水稻品种的反应特性作了研究。观察到早中稻品种在不同的光温互作下,生育期发生变化,但对光温感应的强度无明显影响。而晚稻品种则不仅生育期变化,而且感光性和感温性的强度亦发生显著变化,即随温度降低感光性增强,随日长加长,感温性增强。根据平均每生长一叶片需要的积温与光温关系的研究,发现两种基本类型,即长日低温生长节能型和短日高温生长节能型,早中稻多属前者,晚稻多属后者。并对其适应意义作了讨论。 |

| Abstract: |
| Studying interaction of light and temperature in 21 rice varieties which were designed by 3 temperature and 4 daylengh conditions.Growth duration are varied but intensity of photo and thermo sensitivity are not varied under interaction of photic and thermal conditions were observed in early and middle maturity rice varieties.The G.D.are not only va- ried but also photo-thermo-sensitivity are varied under same condi- tions which likes above.The basic regularity are as follows:the tem- perature are decreased,... |
