摘要： 在光学显微镜、电镜扫描观察中,根据形态上易于分辨的特征,将油菜花芽分化过程划分为八个时期15个阶段。分化的顺序是花萼原基、雄蕊原基、雌蕊原基、花瓣原基和蜜腺原基。主基花芽分化与叶龄数关系密切。上海适期播种的甘蓝型油菜,主茎花芽开始分化时的叶龄数平均为9.8(9～11),主基总叶数(包括叶痕、绿叶及在电镜中能分辨出

Abstract: The patterns of the differentiation and formation of floral organsin rape(Brassica napus)were observed by using light microscope andscanning electron microscope.On the basis of the morphological changesof the floral buds the differentiation phase can be devided into 8 stagesand 15 sub-stages.The 8 s
