花芽分化的迟早和花芽数量的多少与油菜产量形成关系极大。过去对这一问题的研究多偏重于对油菜花芽分化各阶段的形态描述和阶段的划分,而对花芽分化迟民 花芽数量消长。以及花芽分化与油菜生长发育和产量形成的关系则研究不够。因此我们着重围绕这方面作了一些工作。 材料与方
The sooner or later flower bud differentiation and the number of flower buds have a great relationship with the yield of rape. In the past, the research on this issue mostly focused on the morphological description and stage division of rape flower bud differentiation stages, while the number of late flower buds on flower bud differentiation and decline. And the relationship between flower bud differentiation and rape growth and yield formation is not enough. Therefore, we have focused on doing some work in this area. Material and side
