Abstract: The effects of four arbuscular mycorrhizal fungi Glomus mosseae, Acaulospora delicata, Paraglomus occultum and Glomus etunicatum on growth and selenium accumulation of peach [Prunus persica (L.) Batsch] seedlings were studied by a pot experiment. The results showed that application of Acaulospora delicata increased the biomass of peach seedlings, promoted the growth of peach seedlings, and increased the biomass of the root and aboveground parts of peach seedlings by 11.28% and 9.18%, respectively, compared with no application. It also increased the content of photosynthetic pigments, peroxidase activity and catalase activity to a certain extent. Application of Glomus mosseae, Paraglomus occultum and Glomus etunicatum decreased the biomass, photosynthetic pigment content and antioxidant enzyme activity of peach seedlings or had no significant effects on them. Application of Acaulospora delicata also increased the total selenium content and organic selenium content in peach seedlings to a certain extent, and the total selenium content and organic selenium content in shoots increased by 8.01% and 9.34%, respectively, compared with no application. Application of Glomus mosseae, Paraglomus occultum and Glomus etunicatum decreased the total selenium and organic selenium contents in peach seedlings or had no significant effects on them.

Key words: arbuscular mycorrhizal fungi, peach[Prunus persica (L.) Batsch] seedling, selenium accumulation, growth, physiology
