| 摘要: |
| 本文对155个中国水稻品种的光温多元回归作了研究,并对光温与生育期的相关性作了估算。一般而言,早中稻的生育期与温度的关系较密切,晚稻的生育期与日长的关系较大。品种光温回归模型是进一步研究水稻光温反应的各种特性、适应性和分类的基础。 |

| Abstract: |
| The multiple regression of photo-thermo-sensitvity in 155 Chinese rice varieties were studied and the correlation between growth duration and temperature or daylength was estimated in this paper.General speaking,there was significant correlation between G.D.and tempera- ture in early and middle rice varieties,but the significant correlation between G.D.and daylength was present in late-maturing rice varie- ties.The model of regression of photo-thermo-sensitivity in rice varie- ties is a basis on which the c... |
