| 摘 要： | 通过对寒地超级稻种子在不同温度下的发芽试验，结果表明；超级稻种子发芽率与温度关系密切．随着积温的增加水稻种子的发芽率也增加，但积温对发芽的影响程度因品种而异。超级稻品种龙稻5号发芽受积温的影响最大，临界发芽温度也较高；相比之下超级稻品种松粳9号和龙粳14发芽受积温的影响较小，临界发芽温度也较低。

| Abstract: | The experiment of germination of super-rice in cold region was carried out under the different air temperatures. The results showed that thcre was a intimate relationships between the germination percentage and accumulated temperature,the germination percentage improved with the increase of the accumulated temperature, and there was difference among the varieties. The accumulated temperature made the most important effect on the germination of super-rice Longdao No. 5 ,and the critical temperature for germination was the highest. The accumulated temperature made less effect on the germinations of super-rice Songjing No. 9 and Longjing No. 14,and the critical temperatures for germinations were lower than Longdao No. 5. |
