| 摘 要： | 通过对优质食用稻品种爱华5号进行不同播种期处理，研究在不同气候条件下，其籽粒灌浆特性与整精米率的变化规律。结果表明：优质食用稻籽粒灌浆后20d日平均温度在27.9~29.8℃时，籽粒灌浆前、中期速度快，后期速度慢，整精米率相对较低；籽粒灌浆后20d日平均温度在25.2~25.9℃左右时，籽粒灌浆前、中期速度慢，后期速度快，整精米率相对较高。

| Abstract: | The grain filling traits and percentage of head milled on high quality rice variety Ai-hua 5 by different seeding stage were studied. Results showed that the grain filling rate were faster in prophase and metaphase of filling stage than anaphase, when the date of average temperature preponderate ranges 27.9℃ to 29.8℃ after heading stage 20d. But when the date of average temperature preponderate ranges 25.2℃ to 25.9℃ after heading stage 20d, the results were reverse. |
