Bacillus aquimarisstrain DY-3 improves salt-tolerance of tobacco seedlings
Effects ofBacillusaquimaris strain DY-3 on the growth and physiobiochemical characteristics of to-bacco seedling under salt stress were studied by a pot experiment. The results showed that compared with salt stress, shoot length, root length, fresh and dry weights were signiifcantly promoted, chlorophyll content, leaf relative water content, proline content and total phenolic compound content were also signiifcantly enhanced by inoculation withBacillusaquimaris strain DY-3, while lipid peroxidation levels, cell membrane permeability and sodium ion and chloride ion contents were signiifcantly decreased. The above results indicate that inocula-tion withBacillusaquimaris strain DY-3 can enhance the salt tolerance of tobacco seedlings.
