| 摘 要： | 以油菜菌核病菌、番茄灰霉病菌、番茄叶霉病菌为指示菌,采用生长速率法对94株土壤放线菌进行抑菌活性筛选。发现AXW4-1菌株等10株放线菌发酵液至少对3种病原真菌中的1种有60%以上的抑制率,占总测试菌株的10.64%。对这10株放线菌进行抑制孢子及菌核萌发试验,结果获得4株活性较高的菌株,其中AXW4-1和HVA29-2菌株发酵液对番茄灰霉病菌的孢子萌发抑制率分别为86.9%和78.8%,X-1-8和GSA26-2菌株发酵液10倍稀释液对油菜菌核病菌的菌核萌发抑制率均为86.1%;油菜叶片组织法试验表明,X-1-8和GSA26-2菌株发酵液对油菜菌核病的药效均在90%以上。

| Abstract: | Antagonistic function of 94 strains antagonistic actinomycete on Sclerotinia sclerotiorum,Botrytis cinerea,and Fulvia fulva was studied.Antagonistic tests showed that 10 strains of which have better antagonistic action against three pathogens,and the inhibition rates were more than 60 %.The results of spore germination test showed that the inhibition rate of strains AXW4-1 and HVA29-2 were 86.9% and 78.8% to Botrytis cinerea respectively,and strains X-1-8 and GSA26-2 were 86.1% to germination of sclerotia.T... |
