摘要:
通过竞争结瘤试验研究紫云英根瘤菌不同菌株间的竞争结瘤能力,以紫云英宁波大桥品系为宿主植物,7株分离自不同生境紫云英根部瘤体内的菌株与中慢生华癸根瘤菌7653R为研究对象,采用单独接种、与7653R菌株1 ∶[KG-*3]1混合接种方式,在30 d时采样,统计根瘤数量、根瘤质量、不同菌株的占瘤率、定殖能力等。结果发现,紫云英根瘤菌2号菌株的竞争能力与7653R相当,其他菌株的竞争性都不同程度地弱于7653R,尤其是1号菌株的定殖能力最弱,仅是7653R占瘤率的9%。在同时含有2种根瘤菌的瘤体内,7653R和竞争菌株的数量比例相近。不同生境根瘤菌的竞争结瘤能力存在差异,试验同时获得了1株与经典菌株7653R竞争能力相当的紫云英根瘤菌菌株。
