选择交城骏枣(Zizyphus jujube cv.Jiaocheng Junzao)作为分离内生细菌的材料,从中共分离到18株内生菌株,运用平板对峙法从中筛选出5株对大枣病原菌及部分植物病原菌有拮抗作用的内生细菌。抑菌试验结果表明:筛选出的5株细菌对刺盘胞菌Colletotrichum gloeosporides、链格孢菌Alternaria alternata、尖孢镰刀菌Fusarium oxysporium、烟草赤星病菌Alternarial longipes、稻瘟病菌Pyricularia oryzae、人参立枯病菌Rhizoctonia solani、人参菌核病菌Sclerotinia schinseng和小麦根腐病菌Bipolaris sorokiniana均有一定的抑菌活性。对这5株内生细菌进行了形态特征观察和生理生化鉴定。
Zizyphus jujube cv. Jiaocheng Junzao was selected as the material for isolating endophytic bacteria, 18 endophytic strains were isolated from the Chinese Communist Party (CCP), and 5 strains of antagonistic pathogenic fungi and some plant pathogens were screened out by using the slab confrontation method The role of endogenous bacteria. The results of antibacterial test showed that the five strains of bacteria were highly sensitive to Colletotrichum gloeosporides, Alternaria alternata, Fusarium oxysporium, Alternarial longipes, Pyricularia oryzae, Rhizoctonia solani, Sclerotinia schinseng and Bipolaris sorokiniana had some antibacterial activities. The five endophytic bacteria were observed morphologically and biochemically.
