Abstract: (55 Views)
Soil salinity often hinders the productivity of plants in natural and agricultural environments. The symbiosis of arbuscular mycorrhizal fungi (AMF) as a biological fertilizer can increase the salinity tolerance of plants. This study was conducted in order to investigate the effect of inoculation with mycorrhizal fungi on reducing the adverse effects of salinity stress in Iranian violets. Evaluation of the interaction effect of AMF symbiosis at three levels (without symbiosis, Glomus mosseae and Glomus intraradices) and salinity stress treatment at four levels (control, 50, 100 and 200 mM) on the growth and physiological responses of Iranian violets as a factorial layout based on a complete randomized design with three repetitions were performed. Inoculation plants had higher shoot and root biomass, carotenoid and colonization in the presence of different salinity levels. The highest amounts of total chlorophyll (1.70 mg/g fresh weight), antioxidant activity (66.56 mg/g fresh weight), flavonoid (244.05 mg/g fresh weight), phenol (28.46 mg/g of fresh weight), and ascorbate peroxidase activity (103.16 units) were observed in the treatment inoculated with G. mosseae fungus at 200 mM salinity concentration. The lowest amount of electrolyte leakage was obtained in the treatment with G. mosseae fungus in the condition without salt (18.04%). The results of the research showed that the inoculation of host plants with mycorrhizal fungi, especially G. mosseae species, had an effect on plant growth and physiology, and the positive effect of inoculating plants with fungi was significant in the conditions of plant salinity stress.
