摘　　要：从野生沙棘的根部分离出一株内生真菌SJ1,利用该真菌菌丝提取物对玉米,水稻,大豆处理后进行作物试验,选取其重要生育指标作为测定的数据,结果表明SJ1提取物对玉米,大豆,水稻都有一定的促进作用,能够促进作物根系发育,增加产量。根据其形态学及遗传分析鉴定SJ1菌株为宛氏拟青霉(Paecilomyces variotii)。关于拟青霉属的促生作用的研究相对较少。Isolated a strain endophytic fungi SJ1 from the root of wild sea buckthorn.After dealing with corn, rice and soybean by the fungal extracts ,measured some important indicator as data.Results show that the ex-tracts of SJ1 on soybean,maize and rice has a positive effect,and can promote the development of the root of plant ,increased yield.According to its morphological and genetic analysis of SJ1 strain was identified as Paecilomyces variotii.Study on the growth promoting effect of Penicillium is relatively small,SJ1 identification provides a new strain resource for biological pesticide.
