| 摘 要： | 为了明确根际细菌对杨树耐盐能力的影响,采用盆栽方法研究了不同浓度NaCl胁迫下,根际细菌Bacillus sp.和Arthrobacter sp.对杨树生长和生理的影响.结果表明,Bacillus sp.对杨树株高没有明显的影响;在无NaCl或NaCl浓度为85.5 mol/L时,显著降低杨树叶片细胞膜透性;在NaCl...

| Abstract: | To identify the effect of rhizobacteria on salt tolerance of poplars,the impact of plant growth promoting bacteria(PGPR)-Bacillus sp.and Arthrobacter sp.on growth and physiology of poplars seedlings have been investigated in pot experiment.The inoculation of Arthrobacter sp.significantly increased the height of poplar seedlings grown in the presence of 119.7 mmol/L NaCl salt;Bacillus sp.had no obvious impact on height of poplar seedlings stressed by different NaCl concentrations.The two bacteria decreased t... |
