| 摘 要： | 对甘蓝型油菜4个品种不同叶龄期幼苗进行一次自然低温处理,观察低温对花芽分化的促进作用,从而确定油菜对低温的敏感期。结果表明,不同叶龄期幼苗经低温处理后花芽分化均有提早,偏冬性冬油菜和半冬性冬油菜7—8叶和9—10叶幼苗对底温最为敏感,参试的春油菜品种以7—8叶幼苗对低温最为敏感。

| Abstract: | The seedlings in different leaves age of 4 varieties(B.napus)were treatm-ented in low temperature,and the effect of low temperature on bud differentiation was observed,Thereof sensitive stage to low temperature in rape was determented.The results for 2 years showed that,the days from emergence to bud differentiation with low temperature treatment were early than without low temperature treatment in seedlings of 4 varieties.The sensitive stage to low temperature of winter rapeseed cultivars with winterness and weak winterness was 7-8 or 9-10 expanded leaves.The sensitive stage to low temperature of spring rapeseed varieties in this study was 7-8 expanded leaves. |
