于油菜初花期与盛花期采取油菜不同部位花瓣和花药进行真菌分离.除菌核病菌(Sclerotinia sclerotiorum)外,还以不同的频率分离到葡萄孢菌(Botrytis spp.),交链孢菌(Alternaria spp.),芽枝霉菌(Cladosporium spp.),叶点霉菌(Phyllosticta sp.),附球孢菌(Epicoccum sp.),镰刀菌(Fusarium spp.).其中葡萄孢菌、交链孢菌、芽枝霉菌出现较早,为初花期主要真菌群;盛花期还分离到叶点霉菌和附球孢菌,以镰刀菌出现最迟.1991年从分离真菌中选择101个菌株.通过培养皿法和花瓣法测定对菌核菌的拮抗作用,初步筛选出A_3,A_(25),A_(26),B_(10),B_(13),B_(11),B_(26),B_(31),B_(3(?)),C_8,E_1和E_2 12个对菌核菌...

Various fungi were isolated from petals and stamens of rape which were co-llected from early March to late April at emerging-bloom and full-bloom stages.Beside S.sclerotiorum,there were other fungi,such as Botrytis spp.,Alternaria spp.,Cladosporiumspp.,Phyllosticta sp.,Epicoccum sp.,Fusarium spp..At emerging-bloom stage Botrytisspp.,Cladosporium spp.and Alternaria spp.were the dominant mycoflore,but at full-bloomstage Fusarium spp.were frequently isolated.In 1991,101 isolates were selected from thesefungi to test their antagonistic effect to S.sclerotiorum by the methods of culture and petals....
