| 摘 要： | 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。

| Abstract: | 43 Rhizoctonia solani isolates were isolated from the infected turf-grasses of 6 species,Lolium perenne,Poa pratensis,Festuca arundinacea,Agrostis palustris,Cynodon dactylon,and Zoysia japonica,in transition zone of warm season turf to cool season turf,including Shanghai city,Zhejiang province,Shandong province,Henan province and Shaanxi province,during 2003 to 2005.Anastomosis group testing of R.solani were conducted by Parmeter's methods.The results showed that AG1-1A,AG1-1B,AG2-1,AG2-2ⅢB,AG2-2Ⅳ,AG-4 and AG-5 were confirmed in the R.solani isolates of turf-grasses from 5 provinces in China.The dominant anastomosis groups were a bit of difference among the different provinces and turf-grasses,however,AG-1 and AG-2 were the main type.AG1-1B and AG2-1 are the first reported anastomosis sub-groups of R.solani infecting turf-grasses. |
