The influence of Arbuscular mycorrhizal fungi on seedling growth and physiological and biochemical characteristics of Paeonia suffruticosa was studied in this paper. Potted 'Feng Dan' which taken from Heze Tree-peony Garden were inoculated with different AM fungi Glomus mosseae, Glomus versiforme and Glomus intraradices, and the non-inoculated was the control group. The results showed that: the infection rate of different AM fungi was different, and the highest infection rate of G. mosseae was 48.3%. AM fungi could promote the growth of P. suffruticosa seedlings. The dry weight of plants inoculated with G. mosseae was increased 69.5% than that of control, and there was significant difference. AM fungi increased the contents of chlorophyll, soluble sugar, soluble protein, mineral elements N, P, K and nitrate reductase activity. The effects on soluble protein and nitrate reductase activity were of the most significance. The correlation analysis showed that dry weight had extremely significant correlation with the mycorrhizal colonization, nitrate reductase activity and chlorophyll content, and had significant correlation with soluble sugar and soluble protein. G. mosseae was the optimal strain for P. suffruticosa. |
