【摘要】 利用选择培养基对茂名市郊区种植的成熟小白菜植株进行内生菌分离,共得到3株内生细菌、5株内生真菌、2株内生放线菌。细菌分属芽孢杆菌属、埃希氏菌属、黄色杆菌属,真菌主要为曲霉属、毛霉属,放线菌分属链霉菌属和诺卡菌属。利用平板对峙培养法筛选出2株内生放线菌及1株内生细菌对植物菌核病菌有强拮抗作用。更多还原

【Abstract】 Three endophytic bacterial strains,five fungi strains and two actinomyces strains were separated from mature pakchoi plants collected from Maoming suburb by selective media.These strains were preliminarily classified as Bacillus Cohn,Flavobacterium,Escherichia Castellani,Aspergillus,Mucor,Streptomyces and Nocardia.Among the eight isolated genera,two actinomyces strains and one bacterial strain had strong antagonism against Sclerotinia sclerotiorum confront antibiotic culture.更多还原
