摘 要 ：甘蓝型油菜作母本与白菜、甘蓝、黑芥、芥菜型油菜和埃塞俄比亚芥杂交时,花粉粘合程度减弱。花粉管常常不能穿入柱头,与花粉管接触的柱头乳突细胞内普遍产生胼胝质。少数异源花粉管能穿过柱头进入花柱,但时有异常胼胝质沉积在花粉管中。海甘蓝的花粉很难粘合在甘蓝型油菜柱头上。异种花粉与甘蓝型油菜雌蕊的亲和性按大小依次

Abstract:In the cross pollinations between Brassica napus,which was used as female parent,andB.campestris,B.oleracea,B.juncea and B.carinata,the binding degree of pollen grainswas weakened,pollen tubes usually failed to penetrate papillose cells in which callose deposited.Sometimes,a few of alien pollen tube
