This study was to examine the growth of Alnus hirsuta seedlings after artificial inoculation with two kind of VA-mycorrhizal fungi, Glomus mosseae and Gigaspora sp., under three different soil textures, sandy soil, loamy soil (sandy: clay = 1 : 1, v/v), and clay soil The seedlings inoculated with Glomus showed the increased leaf area, leaf number height growth, photosynthetic activity, and nutrient absorption. The dry weight was 4.5 or 4.7 times heigher than that of control in sandy soil and clay soil, respectively. However, the growth in loamy soil response was not greater than the control. The nutrients absorption was increased by Glomus inoculation. The growth and nutrient absorption were not improved by Gigaspora inoculation, indicating that the mycorrhizal association between Alnus and Gigaspora was poor. The differences in nutrient concentration were not significant between mycorrhizal and non-mycorrhizal seedlings in all soil textures. Glomus showed high inoculum rate and increased the Alnus growth. Whereas Gigaspora showed poor hyphal development and did not affect the growth of Alnus. The results obtained in this study indicated that careful selection of best strain of VA-mycorrhizal. fungi and proper soil texture are recommended to improve the growth of Alnus seedlings.
