Han Qing

Abstract

In current study, the regulation of Bacillus subtilis GB03 to seed germination, growth and salt tolerance of Medicago sativa was investigated. The results indicated that B. subtilis GB03 significantly increased seed germination potential and germination rates of M. sativa under various salinity conditions. GB03 improved shoot height, root length and plant biomass in different degrees, and significantly enhanced chlorophyll content under different concertrations of salt.
