【目的】筛选和鉴定从威廉斯香蕉抗枯萎病株系根、球茎及假茎分离得到的可抑制香蕉枯萎病菌(Fusarium oxysporum f.sp.cubense,Foc)内生菌,研究其抑菌促生效果。【方法】通过16S rRNA基因序...展开更多 【目的】筛选和鉴定从威廉斯香蕉抗枯萎病株系根、球茎及假茎分离得到的可抑制香蕉枯萎病菌(Fusarium oxysporum f.sp.cubense,Foc)内生菌,研究其抑菌促生效果。【方法】通过16S rRNA基因序列测定和生理生化试验,对香蕉抗枯萎病株系内生菌进行种类鉴定和系统发育分析;通过平板对峙试验检测各菌株的抑菌能力,探究拮抗菌分泌抑菌相关活性物质的种类;采用盆栽试验对香蕉抗枯萎病株系内生菌进行生防...

【Objective】To screen and identify endophytic bacteria that can inhibit Fusarium oxysporum f. sp. cubense (Foc) isolated from roots, bulbs and pseudostems of wilt-resistant strains of Williams banana, and study their inhibitory and growth-promoting effects. 【Method】Through 16S rRNA gene sequence and physiological and biochemical tests, species identification and phylogenetic analysis of endophytic bacteria in banana fusarium wilt resistant strains were carried out. The plate confrontation test was carried out to detect the antibacterial abil...
