Abstract: (38 Views)
An effective solution for ameliorating the heavy metal toxicity in food plants is endophytic microorganisms. For this reason, the present research was studied the effect of endophytic fungi on morphological characteristics improvement, photosynthesis pigments and the rate of cadmium toxicity in shoot and root of radish (Raphanus sativus L.) planted in cadmium contaminated soil. The experimental treatments included cadmium (in three levels: 0, 25 and 100 mmol) and symbiosis fungi, Priformospora indica and Glomus mosseae inoculation (in four levels: control (non inoculation), incubation with P. indica (Pi), incubation with G. moseae (Gm) and co-incubation with (Pi + Gm), which was done as factorial based on randomized design in three replications in a pot experiment in a greenhouse. The results showed that, in radish, the vegetative traits and chlorophyll a and b had a high downward trend with increasing cadmium concentration. In the study, inoculation of radish plants with P. indica and G. moseae improved morphological, physiological and biochemical characteristics. The symbiosis of radish with endophytic fungus caused an increase in morphological traits such as fresh and dry weight of roots and leaves, plant height and root length through improved absorption of water and nutrients. Also, the symbiosis relationship of radish with endophytic fungi increased antioxidant enzymes activity, total phenol and flavonoid, lowered lipid peroxidation and caused higher vegetative growth due to decreased cell damage. Treatment of the plant with P. indica and G. mosseae, especially the co-treatment (Pi+Gm), caused an induced systemic resistance in radish enhancing antioxidant compound activities and a reduction in lipid peroxidation.
