玉米大斑病拮抗细菌的分离与筛选

Isolation and Screening of Antagonistic Bacteria to Setosphaeria turcica

采用土壤稀释法从玉米根际土壤中分离得到1 182株细菌菌株,从中筛选对玉米大斑病菌具有较强拮抗的菌株24个。对24株拮抗菌抗菌谱的测定结果表明,KD16-13、KJ2-01对水稻稻瘟病菌、马铃薯早疫病菌、水稻纹枯病菌、尖孢镰刀菌、禾谷镰刀菌、链格孢菌、番茄枯萎病菌具有较强的拮抗作用且抑菌效果明显。

Totally 1182 bacterial strains were isolated from corn rhizosphere soils, of which 24 strains were an tagonistic to Setosphaeria turcica. KD1613 and KJ201 strains showed antibiosis activity to phytopathogenic fungi, such as Pyricularia grisea, A lternaria solani, Rhizoctonia solani, Fusarium oxysporum, Fusarium graminearum, Al ternaria alternate, Fusarium wilt.
