摘要: 【目的】调查分析不同产地及不同品种大蒜内生菌的群落多样性,测定内生菌对5株病原菌的拮抗作用。【方法】以新疆、山东的白皮蒜、红皮蒜为研究材料,采用BIOLOG生态板法和培养基培养法进行大蒜内生菌群落多样性的分析,并利用平板对峙法,利用大蒜内生菌对立枯丝核菌(Rhizoctonia soleni)、棉花枯萎病菌棉花枯萎病菌 (Fusarium oxysporumf)、扩展青霉 (Penicillium expansum)、大肠杆菌(Escherichia coli)、金黄色葡萄球菌(Staphyloccocus aureus)的拮抗作用进行研究。【结果】不同品种来源的大蒜内生菌群落代谢活性均较低,但不同类型碳源利用活性存在明显分布规律;初步筛选获得的45株内生菌,分属于芽孢杆菌属(Bacillus)、类芽孢杆属(Paenibacillus)、链霉菌属(Streptomyces)、拟诺卡氏菌属(Nocardiopsis) 和迪茨菌属(Dietzia) 等5个属15个种,其中芽孢杆菌属菌株占绝大部分,占85%以上,且在不同大蒜样品中均为优势菌,但种间分布存在着差异。获得了24株具有拮抗作用的内生菌菌株。【结论】大蒜内生菌群落多样性较为简单,存在着具有拮抗作用的微生物资源,有待进一步开发利用。

Abstract: 【Objective】 In order to investigate diversity of the endophytes in Garlic varieties from different producing area, and obtain antagonistic microbes.【Method】Garlic varieties, white garlic and red garlic from different producing areas were sampled. And then, Biolog Eco method was employed to investigate metabolic characteristics of endophytes. Meanwhile, Endophytes were isolated and antagonistic bacteria to Rhizoctonia soleni,Fusarium oxysporumf,Penicillium expansum,Escherichia coli and Staphyloccocus aureus were screened.【Result】Low metabolic activity of endophytes in Garlic were determined, and some differences in the utilization and diversity in Garlic varieties from different producing areas were analyzed. 45 endophytes were isolated which were involved in 15 species belonging to genus Bacillus, genus Paenibacillus , genus Streptomyces , genus Nocardiopsis , and genus Dietz . Isolates in Genus Bacillus were dominant in Garlic endophytes, accounted for more than 85%, but there were differences in the distribution of species. Additionally, lots of antagonistic bacteria were obtained. 【Conclusion】Diversity of the endophytes in Garlic varieties from different producing area were all poor, but effective resource of antagonistic microbes needs further explore.

Key words: Garlic varieties; different producing areas; endophytes; antagonistic microbes
