摘要
[目的]探索植物根际促生菌对金线莲生理特性的影响,为金线莲产业的可持续发展提供新思路。[方法]运用3株植物根际促生菌(蜡样芽孢杆菌H-15、阿耶波多氏芽孢杆菌H-6、伯克氏菌P_(4)),通过盆栽试验,研究其对金线莲生长的影响。[结果]根际促生菌H-15、H-6、P_(4)处理下金线莲的存活率分别比CK增加了40%、22%、39%;发病率分别比CK降低了22%、33%、11%;鲜重增加率分别是CK的2.57、1.60、1.74倍;与此同时,3株根际促生菌处理下金线莲中多糖含量显著高于CK,P_(4)处理下的总黄酮含量和微量元素含量均高于CK,而3株根际促生菌处理下金线莲的游离氨基酸含量均低于CK,分别比CK下降了29%、11%、23%。[结论]植物根际促生菌能显著促进金线莲生长,具有良好的应用潜力。
[Objective]To explore the effect of rhizosphere promoting bacteria on physiological characteristics of Anoectochilus roxburghii,and to provide new ideas for sustainable development of Anoectochilus roxburghii industry.[Method]Three plant rhizosphere promoting bacteria(Bacillus H-15,Bacillus H-6 and Burkholderia P_(4))were used to study their effects on the growth of Anoectochilus roxburghii through pot experiments.[Result]Compared with CK,the survival rate of Anoectochilus roxburghii treated with H-15,H-6 and P_(4) increased by 40%,22%and 39%,respectively;the incidence decreased by 22%,33%and 11%,respectively;the fresh weight increase rate was 2.57,1.60 and 1.74 times of CK,respectively.At the same time,the polysaccharide content of the treatments treated with rhizosphere promoting bacteria was significantly higher than CK,the total flavonoids content and microelement content under P4 treatment were all higher than CK,while the free amino acids content were all lower than CK,which decreased by 29%,11%and 23%,respectively.[Conclusion]Rhizosphere promoting bacteria can significantly promote the growth of Anoectochilus roxburghii and have bright application prospects.
