Study on Arbuscular Mycorrhiza Fungi Diversity and Inoculation Effect of Prunus mongolica
Mycorrhizal status of Prunus mongolica of western Inner Mongolia in the desert region was studied by observing the ectomycorrhiza morphological and the arbuscular mycrrhizal structure of the nutritive root.Ectomycorrhiza colonization was not found in the present study, while arbuscular mycrrhiza colonized quite well, and the highest frequency of colonization was 97％. Eleven arbuscular mycorrhizal fungi species of four genera and one uncertain species were identified by the morphologiacal identification of the spores, among which Acaulosopra rehmii and Glomus mosseae were the dominant species. In addition, Glomus mosseae and Glomous versiforme were inoculated on Prunus mongolica, and the result showed that the nutritive root of Prunus mongolica and the Glomus mosseae could form the typical arbuscular mycrrhizal structure as hyphae,vesicles and arbuscular, but not with the Glomous versiforme. Glomus mosseae promoted the growth of Prunus mongolica.
