摘要
[目的]探讨PGPR引发对紫花苜蓿幼苗耐盐性及其生理效应的影响。[方法]用3种不同植物生长促生菌溶液喷施紫花苜蓿幼苗,研究在75 mmol/L Na2CO3胁迫下不同植物生长促生菌对紫花苜蓿幼苗生理生化特性的影响。[结果]与对照相比,施用不同植物生长促生菌处理的紫花苜蓿幼苗其叶绿素、游离脯氨酸、可溶性糖、可溶性蛋白含量均有不同程度的升高,其中CS3菌液处理效果最好。[结论]植物生长促生菌能够促进紫花苜蓿的生长特性发育,并能提高其抗逆性。
[Objective]The study aimed to explore the influences of Growth-promoting rhizobacteria（PGPR） on salt tolerance and physiological effect of seedlings of Medicago sative Linn.[Method]Three different kinds of growth-promoting rhizobacteria solutions were used to spray on M.sative seedlings and the influences of different kinds of growth-promoting rhizobacteria on physiological and biochemical characteristics of M.sative seedlings under 75 mmol/L of Na2CO3 were studied.[Result]Compared with the control group,the chlorophyll,free proline,soluble sugar and soluble protein content of M.sative seedlings treated with different kinds of growth-promoting rhizobacteria were increased,while the effect of CS3 treatment was the best.[Conclusion] The growth-promoting rhizobacteria could promote growth and development of M.sative as well as increased its resistance.
