Effect of arbuscular mycorrhizal fungi (AMF) on accumlation capability for Se and photosynthesis characteristics of Actinidia chinensis ‘hongyang' leaves

A pot experiment was conducted to investigate the effects of five different arbuscular mycorrhizal fungus (Glomus versiforme, Glomus geosporum, G. Mosseae, Glomus etunicatum and Glomus diaphanum) on the accumlation capability for Se, the content of polysaccharide and photosynthesis characteristics on the condition of soil apllied with Na2SeO3 (100mg/L) . Correlation analysis was carried on. The results showed that G. mosseae, G. Versiforme and Glomus etunicatum inoculation treatments significantly increased the content of total Se in ‘hongyang' kiwifruits leaves (p<0.05) . Among the above treatments, the best efficiency were showed in G. Mosseae which was equivalent to 1.22 times of the control group. Yet G. Geosporum and G. Diaphanum significantly improved the content of organic Se in ‘hongyang' kiwifruits leaves, and with 1.15 times of the control group, the efficiency of G. Geosporum inoculation treatment was the best. On the other hand, all five different arbuscular mycorrhizal fungus inoculation treatments significantly improved the content of polysaccharide and photosynthesis characteristics, among them, G. versiforme1 inoculation treatment had the best effect.
