为了研究镉胁迫下植物促生菌密歇根克雷伯氏菌Klebsiella michiganensis TS8和Lelliottia jeotgali MR2对拟南芥Arabidopsis thaliana生长及镉富集的影响,文中以野生型拟南芥为试验材料,将其种植在不同镉浓度土壤基质中,并施入MR2和TS8菌悬液。低浓度镉处理组（LC）为购买的基质营养土,初始镉浓度为14.17mg/kg,高浓度处理组（HC）为在购买的基质营养土上额外喷洒200 mg/kg Cd2+。结果表明相比对照组,不同浓度镉胁迫下喷施MR2菌悬液均可显著促进拟南芥的生长,而TS8和MR2 TS8混合菌液仅在高浓度镉胁迫下表现出一定的促生效果。但值得关注的是不同浓度镉胁迫下TS8菌悬液可显著降低拟南芥的地下部对...

In this study, the effects of two plant growth-promoting bacteria Klebsiella michiganensis TS8 and Lelliottia Jeotgali MR2 on the growth and cadmium (Cd) uptake of Arabidopsis thaliana under Cd stress were explored. A wild-type Arabidopsis thaliana was selected as the experimental plant and was planted at different Cd concentrations. MR2 and TS8 bacterial suspensions were sprayed onto the rhizospheric soil during the planting process. The initial Cd concentration of the bought soil was 14.17 mg/kg, which was used as the pot soil of the low-conc...
