Abstract
The effects of AM fungi on the growth and protective enzymes in cotton plants inoculated Glomus mosseae and Glomus caledonium under salt-caused stress conditions was studied at the levels of 0,0.1%,0.2%,0.3% NaCl added to the soil for the potted plant. The results showed that application amount of NaCl significantly influenced the growth of cotton plants and inoculation effect of AM fungi. After inoculation mycorrhizal infection rate was promoted, and total dry weights and output of cotton were increased, which was the best under applying 0～0.2% NaCl density. Leaf syn-pigment significantly increased in the period of showing buds and 0～0.1% NaCl density. The content of soluble protein and activity of protective enzyme, such as SOD, POD and CAT increased in the pregnant later period and 0.2%～0.3% NaCl density. The content of K, Ca and Mg varied with the position of plant and NaCl density. It could be concluded that the mechanism of AM fungi strengthening the salt tolerance of cotton plants may be the direct role of AM fungal hyphal contribution to soil minerals uptake in mycorrhizal plant, and the indirect role of AM fungi improved mycorrhizal plant interior ionic balance and the physiological metabolic activity and enhanced the activity of protective enzymes.
