| 摘 要： | 为促进寒地超级稻育种并提高其栽培技术水平，以寒地超级稻龙稻5号和同区种植面积较大品种龙稻3号为试验试材，研究其籽粒灌浆的动态变化。结果表明：寒地超级稻龙稻5号籽粒灌浆过程中籽粒重量与抽穗后日数符合Logistic方程，推测其最大千粒重为23．94g，最大籽粒灌浆速率是在抽穗后13d左右出现。

| Abstract: | In order to promote the breeding of super-rice in cold and improve the level of cultivation techniques, taking super-rice Longdao 5 and control variety in the same ecotope Longdao 3 as materials, dynamic change of grain-filling was studied. The results showed that grain weight and the days after heading of Longdao 5 were fitted well with Lo gistic equation,its maximal thousand kernel grain weight was reckoned 23.94 g, the maximum grain-filling rate ap peared after heading for 13 d,and the plant area was large. |
