Objective: The research aimed to evaluate the effects of mycorrhizal fungi on seed germination and seedling transplant survival rate of Rhododendron annae to provide references for exploitation and mycorrhizal cultivation of alpine rose. Method: The mixed mycorrhizal fungi isolated from roots of wild Rhododendron annae was inoculated with different matrix. In different coverage treatments, seed germination and seedling transplant survival rate were studied. Result: The results indicated that seed germination of inoculation treatments was earlier than non-inoculation treatment. Germination potential, germination rate, seedling and their transplant survival rate were remarkably increased by inoculation, and the difference was highly significant. The medium for the highest germination potential was humic soil plus pearlite (3:1) covered with pine needle, which germination potential was 39.00% and germination rate was 72.67%. Humic soil inoculation covered with moss enjoyed the maximum seedling survival rate (88.33%) and its transplant survival rate was 82.21%. Conclusion: Mycorrhizal fungi played a significant role in seed germination and transplant of Rhododendron annae. Humic soil plus pearlite (3:1) inoculation covered with pine needle was better in seeding, and humic soil inoculation covered with moss in transplant.
