| 摘要: |
| 155个中国水稻品种的基础营养生长期属中等的、即40—70天的占60%。中稻比早、晚稻长,籼比粳长。155个中国水稻品种的感温性属8级的、即温度升高1℃,促进生育3.51—5.00天的占一半以上。感温性与熟期类型和纬度之间有正相关关系,形成早弱晚强,北弱南强的变化趋势,发现了一群感温性弱的晚稻品种。 |

| Abstract: |
| Middle basic vegetative phase was observed in ninety three of 155 Chinese rice varieties and the middle maturing rice varieties has the longest BVP.The BVP was longer in Indica than in Sinica. Eighty rice varieties out of 155 were 3 scale thermosensitive.A high positive relationship between thermosensitivity,croping type and the latitudes in which the crop was grown were observed.Varieties grown in the north areas were they follow early maturing were less temper- ature sensitive than those grown in the Sout... |
