2003~2005年,从我国冷季型草坪与暖季型草坪过渡地区的上海市、浙江省、山东省、河南省和陕西省草坪褐斑病的病株样本中,分离得到了43个立枯丝核菌分离物,其寄主包括多年生黑麦草(Lolium perenne)、高羊茅(Festuca arundina-cea)、草地早熟禾(Poa pratensis)、匍匐翦股颍(Agrostis palustris)、结缕草(Zoysia japonica)和狗牙根(Cynodon dactylon)。按照Parmeter等的方法对该过渡带的草坪禾草立枯丝核菌分离物进行了菌丝融合群的测定,结果表明,上述5省(市)草坪禾草立枯丝核菌的菌丝融合群包括AG1-1A、AG1-1B、AG2-1、AG2-2ⅢB、AG2-2Ⅳ、AG-4和AG-5。不同省份、不同寄主草坪禾草的菌丝融合群类型略有不同,主要融合群类型为AG-1和AG-2。AG1-1B和AG2-1是草坪上首次报道的立枯丝核菌融合(亚)群。
From 2003 to 2005, from the cold turf and warm-season turf transitional areas in China, the samples of turf spot in Shanghai, Zhejiang, Shandong, Henan and Shaanxi Provinces were isolated. Rhizoctonia isolates whose hosts include perennial perennials such as Lolium perenne, Festuca arundina-cea, Poa pratensis, Agrostis palustris, Zoysia japonica ) And Cynodon dactylon. According to the method of Parmeter et al., The mycelial fusion population was determined in the Rhizoctonia solani isolates of the transitional zone. The results showed that mycelium fusion of the Rhizoctonia solani in the five provinces The group includes AG1-1A, AG1-1B, AG2-1, AG2-2IIIB, AG2-2IV, AG-4 and AG-5. In different provinces, the types of mycorrhizal fusions in grass of different host lawns were slightly different, and the main fusiform groups were AG-1 and AG-2. AG1-1B and AG2-1 were the first reported Rhizoctonia solani fusions (sub) population in turf.
