摘要:
采用盆栽试验,设置单独接种解淀粉芽孢杆菌[Bacillus amyloliquefaciens(BA)]、枯草芽孢杆菌[Bacillus subtilis(BS)]及其组合接种处理(BA+BS),以不接种处理为对照(CK),探索接种促生菌对金线莲生物活性成分含量及土壤细菌群落的影响。结果表明,培养期内B. amyloliquefaciens、B. subtilis皆可在金线莲根际土壤中存活,且二者组合接种更易形成生物膜。与CK处理相比,BA、BS处理能够分泌铁载体、植酸酶、生长素和玉米素以促进生物量、皂苷和黄酮(槲皮素、山柰酚、异鼠李素)累积,BA+BS处理具有最大值。16S rRNA高通量测序结果表明,与CK处理相比,BA+BS处理下细菌群落具有更高的丰富度,且细菌门、属水平群落结构丰度皆发生了明显变化,以慢生根瘤菌属(Bradyhizobium)、玫瑰弯菌属(Roseiarcus)为主的有益微生物的丰度增加,与病原菌累积相关的黄色杆菌科未分类属(norank_f_Xanthobacteraceae)的丰度显著降低。相关分析结果进一步表明,生物活性成分与相关有益菌属的丰度皆呈显著或极显著正相关,而与norank_f_Xanthobacteraceae的丰度呈极显著负相关。综上,接种B. amyloliquefaciens和B. subtilis可通过增加有益微生物的丰度和降低有害微生物的丰度以改善金线莲的健康和提高生物活性化合物的含量。
