Other claims from this paper (12)
- Intervention effect Bacillus cereus TC012 (BC) treatment significantly increased tobacco plant height by 38.65% in salt-affected soil microcosms.
- Intervention effect Bacillus methylotrophicus TC023 (BM) treatment significantly increased tobacco plant height by 91.94% in salt-affected soil microcosms.
- Intervention effect Bacillus amyloliquefacien TC037 (BA) treatment significantly increased tobacco plant height by 90.66% in salt-affected soil microcosms.
- Intervention effect Plant growth-promoting rhizobacteria stimulated stem girth, seedling biomass and carotenoid of tobacco in salt-affected soils.
- Intervention effect Plant growth-promoting rhizobacteria stimulated chlorophyll in tobacco grown in salt-affected soils.
- Mechanism Salinity changes in tobacco plants mostly depend on improved proline, soluble protein, soluble sugar, protective enzyme activity and K+/Na+ ratios.
- Mechanism Increases in indole-3-acetic acid, zeatin riboside and gibberellic acid promoted tobacco growth.
- Intervention effect Inoculation with PGPR enhanced the activity of laccase, urease and neutral protease in tobacco soil samples.
- Intervention effect Inoculation with PGPR enhanced the activity of acid phosphatase and sucrase in tobacco soil samples.
- Intervention effect Inoculation with PGPR had positive effects on soil physicochemical properties in tobacco cultivation.
- Intervention effect Inoculation with PGPR significantly increased the relative abundance of Pseudomonas and Bacillus in tobacco soil.
- Recommendation PGPR inoculation has great potential to alleviate salt damage in tobacco plants.
