Abstract:

In this study, we inoculated Bromus inermis ‘Wusu No.1’ with arbuscular mycorrhizal fungi (AMF) and determined its effects on the growth characteristics and sugar content of the host plant. A pot experiment was conducted using B. inermis ‘Wusu No.1’ and three AMF species-Funneliformis mosseaeRhizophagus intraradices, and Rhizophagus irregularis. These AMF were inoculated alone or in various combinations onto B. inermis plants. The results show that AMF, whether inoculated singly or co-inoculated, effectively colonized the roots of B. inermis, with colonization rates ranging from 69.83% to 80.29%. Compared with non-inoculated plants, those inoculated with AMF showed higher values for growth indicators and chlorophyll content, and higher values for total root length, root surface area, root volume, root tip number, and root cross number. Among the various treatments, the combined inoculation of F. mosseae and R. intraradices had the most significant effect, increasing the total biomass, total root length, and root surface area by 107.67%, 73.34%, and 79.63%, respectively, compared with the control group. Both single and co-inoculation of F. mosseae and R. intraradices resulted in significantly increased sucrose and glucose contents in the leaves and roots of B. inermis plants, with higher values in the co-inoculation treatment. A comprehensive analysis using the membership function method revealed that the co-inoculation treatment with F. mosseae and R. irregularis yielded the best results in terms of establishing root architecture and improving sugar content in B. inermis.
