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:
Dy namic study of seed filling on So ng jing No . 9 wa s conducted. The results show ed that : The seed filling cha racter of So ng jing No. 9 w as ear lie r , fa ster and more stable than the tw o contr act varieties. I t w as the same a s CKs that the seeds filling velo city on top and low were stable , and reached the maximum after 25 days of heading , but the middle seeds w ere 5 day s la te r than the top and low. The difference was ev ident that the filling velocity o f seeds on differe nt pa rt , the sequence of filling velocity and seed weig ht from stro ng to w eak w as top , middle and low .
