Abstract: Salt is an important environmental factor that affects wheat growth and development and restricts crop production. Bacillus subtilis QM3 is a strain of antagonistic strains which have biological control function. In this paper, the effects of wheat seed, and soaked treatment by B. subtilis QM3, on germination and antioxidant enzyme activities under salt stress were studied. The results showed that under salt stress, B. subtilis QM3 soaking could increase the germination percentage (GP), germination potential (GT), and germination index (GI) of wheat, and significantly increase the activity of catalase (CAT), peroxidase (POD) and superoxide dismutase (SOD) (p
