小克银汉霉属(Cunninghamella)是广泛分布于亚热带地区的主要土壤真菌,而在温带分离频率却较低。该属可以定殖于毛发的髓部(Domsch & Gams,1970)。1991年以色列的 Galper等人报道,用 C.elegans 防治爪哇根结线虫(Meloidogyne javanica)效果比较明显。在对定殖于大豆胞囊线虫(Heterodera glycines)胞囊上的真菌研究中发现,刺孢小克银汉霉(C.echinulata)和雅致小克银汉霉(C.elegans)均可以定殖于 SCN 胞囊上,现作一简要介绍。1 材料与方法1.1 土壤采集和胞囊的分离土壤采集于沈阳近郊大豆地中,用淘洗—过筛法分离出胞囊。
Cunninghamella is a major soil fungus widely distributed in the subtropical region, but isolated at temperate zone. The genus colonizes the pith of hair (Domsch & Gams, 1970). In 1991, Israel’s Galper et al. Reported that C.elegans was effective against Meloidogyne javanica. In studies of fungi colonized on Heterodera glycines, it was found that both C. echinulata and C. elegans could colonize SCN Cysts, now make a brief introduction. 1 Materials and methods 1.1 soil collection and separation of cysts Soil was collected in the suburbs of Shenyang in soybean, panning - sieved separation of the cysts.
