Background and Objective: The production of ornamental plants is of great importance due to their high economic value and aesthetic appeal. Proper plant nutrition plays a crucial role in improving the final product. Biofertilizers, which contain beneficial microorganisms such as fungi and bacteria, enhance plant growth by improving soil properties. This study was conducted to evaluate the effects of three arbuscular mycorrhizal fungi species on some morphophysiological traits of Rosa hybrida (cv. Chiti).
Methods: The experiment was carried out as a completely randomized design with four replications. Experimental treatments included three fungi species and their dual and triple combinations: Funneliformis mosseae, Funneliformis castaneae, Funneliformis margarita, F. margarita × F. castaneae, F. margarita × F. mosseae, F. mosseae × F. castaneae, and F. castaneae × F. margarita × F. mosseae, along with a vermicompost treatment combined with the base substrate (consisted of garden soil, cocopeat, and perlite mixed at 1:1:1 volumetric ratio) and a non-inoculated control. After flower emergence, traits including number of flowers, peduncle length, fresh and dry weights of shoot, fresh and dry weights of root, root length, total chlorophyll content, relative water content, total phenol content, antioxidant capacity, catalase enzyme activity, and root colonization percentage were measured.
Results: Inoculation with different mycorrhizal fungi significantly improved growth and flower quality of rose plants. The highest peduncle length (73.02 mm), number of flowers (6.75 flowers per plant), and shoot fresh and dry weights (62.41 and 30.55 g per plant, respectively) were obtained in the F. castaneae × F. margarita × F. mosseae treatment. Compared to the control, the triple mycorrhizal treatment resulted in increases of 95.9 and 95.8% in root fresh and dry weights, respectively. In addition, total phenolic content and antioxidant capacity increased by 57.8 and 81.7%, respectively, under the triple mycorrhizal treatment compared with the control.
Conclusion: The application of different arbuscular mycorrhizal fungi species, particularly in combined forms, can be an effective strategy for achieving desirable growth indices, enhancing physiological performance, and increasing flowering in hybrid rose plants.
