Abstract:
Using 3 salt tolerant bacteria as materials，and tomato seeds as research objects，tomato seeds were soaked by salt tolerant bacteria fermentation liquid，and the germination rate，number of lateral root，hypocotyl length，root，hypocotyl and cotyledon fresh weights were investigated and analyzed，in order to understand mitigation effect of salt tolerant bacteria on the salt stress in the process of germination of tomato seeds.The results showed that compared with the high salt liquid NA medium treatment，the salt tolerant bacteria fermentation solution had obvious mitigation effect on salt stress during the germination of tomato seeds，the seed germination time，germination rate，the number of lateral root，hypocotyl length，root，cotyledons and hypocotyls fresh weight were improved.Among the above 3 strains，the effects of strain X7 fermentation liquid treatment were significant，and did not found synergistic or antagonistic effect.
