The design was divided into three groups: inoculating with Glomus mosseae (GM), inoculating with Acaulospora delicate (AD), inoculating with inactivated fungi (CK). After determination of parameters such as mycorrhizal infection rate, biomass, root absorption activity, content of mineral elements and resistance related enzymes, results showed: (1) seedlings' root can form mycorrhiza by inoculating with GM and AD; compared with control seedlings, the morphology and biomass of seedlings with mycorrhiza were greatly different and significantly positively correlated with mycorrhizal infection rate (P<0.05). (2) Root activity of seedlings with mycorrhiza increased strikingly and there was significant positive correlation between the ratio of active absorption area in root and the content of N and K (P<0.05). (3) In the peak and late growth periods, the root peroxidase activity in seedlings with mycorrhiza was much higher than that in control seedlings, otherwise much lower than that in control seedlings in the later growth period, indicating a negative correlation (P<0.05). The root polyphenol oxidase activity in seedlings with mycorrhiza was much higher than that in control seedlings (P<0.05), coming to the highest in the peak period, however there was no big difference between seedlings inoculated with different fungi. Results demonstrated that compared with control seedlings, inoculating with fungi increased the root absorption activity and enzyme system activity, but also was good for seedlings resisting to various stresses and of great significance on enhance the distribution region of Elaeagnus mollis Diels.Read More
