| 摘 要： | 通过对不同水稻品种籽粒灌浆动态的研究,结果表明:与两个对照品种相比,优质超级稻松粳9号籽粒灌浆具有启动早、灌浆速率高而且平稳的特点.上部籽粒和下部籽粒灌浆速率平稳,抽穗后25 d灌浆速率达到最大值,与两个对照品种一致;中部籽粒在抽穗后30 d灌浆速率达到最大,晚于两个对照品种.不同部位的籽粒灌浆差异明显,灌浆速率和粒重由大到小依次是上部籽粒、中部籽粒、下部籽粒.

| Abstract: | Dynamic study of seed filling on Songjing No.9 was conducted.The results showed that: The seed filling character of Songjing No.9 was earlier,faster and more stable than the two contract varieties.It was the same as CKs that the seeds filling velocity on top and low were stable,and reached the maximum after 25 days of heading,but the middle seeds were 5 days later than the top and low.The difference was evident that the filling velocity of seeds on different part,the sequence of filling velocityand seed weight from strong to weak was top,middle and low. |
