摘      要：Land salinization is a major form of land degradation,which is not conducive to the growth and quality of fruits and *** salt tolerance can be enhanced by arbuscular mycorrhizal fungi(AMF)or plant growth-promoting rhizobacteria(PGPR).This study examined the effects of inoculation with PGPR singly or in combination with AMF,on the growth and quality of tomato fruits under low saline *** were cultivated in a greenhouse with sterilized soil,inoculated with PGPR,AMF,or co-inoculated with PGPR and AMF,and NaCl solution(1%)was added to the *** results indicated that AMF+PGPR decreased the roots and shoot biomass accumulation,and increased the number and fresh biomass in tomato fruits to a certain extent compared with non-inoculated *** and AMF mediated the level of reactive oxygen and lipid peroxidation,the accumulation of antioxidants,and the activity of antioxidant enzymes,including proanthocyanidins,flavonoids,ascorbic acid,superoxide dismutase,peroxidase,and total antioxidant ***,PGPR,AMF,and PGPR+AMF improved the overall osmotic adjustments and accumulation of soluble sugars and soluble ***,the AMF-Funneliformis mosseae and PGPR-Bacillus subtilis can potentially alleviate the adverse effects of salt stress and be applied as a biofertilizer in agricultural practice.
