番茄灰霉病拮抗内生放线菌的筛选、鉴定及其活性评价OA北大核心CSCDCSTPCD
Screening, identification, and activity assessment of endophytic actinomycetes from tomato plants against Botrytis cinerea
对安徽省淮北市番茄植株根、茎、叶中内生放线菌进行了分离、筛选,并测定了其抑菌活性.结果表明:番茄根、茎和叶中的内生放线菌的数量分别为5.66× 104、0.67×104和0.39×104 CFU·g-1鲜重.根据分离部位和表型特征,从健康番茄植株体内分离到93株内生放线菌,通过对峙实验,筛选到7株对番茄灰霉病菌有拮抗作用的菌株,占所分离内生放线菌总数的7.5％.来自根组织中的菌株HNU-EA27的抑菌效果最佳,抑菌圈直径达28.3 mm.根据形态…查看全部>>
In this study, the endophytic actinomycetes in tomato plants in the farmlands in Huaibei City of Anhui Province were isolated and screened, and the bio-activities of the actinomycetes against pathogenic fungus Botrytis cinerea were determined. The population density of the actino-mycete in the tomato roots, stems, and leaves were 5.66×104, 0.67×104, and 0.39×104 CFU · g-1 fresh weight, respectively. According to the isolation position and phenotype character…查看全部>>
