Abstract
Zinnia (Zinnia elegans) was inoculated with four arbuscular mycorrhizal fungi (AMF) i.e. Gigaspora margarita, Gigaspora rosea, Glomus intraradices, and Glomus mosseae, either singly or mixture of two species of Gigaspora and Glomus. Results indicated that Glomus significantly enhanced the leaf size and the shoot biomass. G. mosseae was more effective than G. intraradices. Only G. mosseae increased number and size of flowers. Mixed inoculations were not much effective in the growth-promotion than the corresponding singly inoculation with Glomus. Comparison of colonization percent demonstrated that the highest colonization by G. mosseae, and followed by G. intraradices and Gigaspora species. In semi-quantitative PCR amplifications, Glomus was dominant in the roots. Our results suggest that G. mosseae is good for inoculation to zinnia and the interaction between different AMF species should be given full consideration in the application.
