Abstract: (55 Views)
Arbuscular mycorrhizal fungi (AMF) reduce the harmful effects of heavy metals on plant growth and performance. Therefore, this study was conducted in the form of a factorial experiment with a completely randomized basic design at three replications with the aim of investigating the effect of Funneliformis mosseae fungus on the response of Periwinkle to cadmium stress. To apply stress, Periwinkle plants were treated with 3 ml of cadmium nitrate solution with a concentration of 10, 20, and 30 mg/l on three occasions with an interval of three days. To apply the fungal treatment, about 50 g of F. mosseae inoculation liquid was added under the roots of the plant in the pot at the time of cultivation. After 3 months from planting, morphological and physicobiochemical traits indicated a concentration-dependent effect of cadmium on Periwinkle traits. F. mosseae fungal treatment led to the improvement of various traits, so that the effect of the fungus on the plant was greater with the increase in stress level. Compared to the mild, moderate, and severe levels of stress (10, 20, and 30 mg/L), F. mosseae led to an increase of 51, 33, and 41% in height, 50, 57, and 35% shoot dry weight, 19, 32, and 45% proline, 18, 52, and 56% chlorophyll, 10, 110, and 25% carotenoids, 17, 47, and 37% membrane stability, 43, 64, and 47 % phenol, 95, 16, and 35% protein, 39, 15, and 63% sugar, 30, 64, and 210% catalase, 15, 31, and 148% dismutase, 19, 1, and 1% peroxidase, and 12, 78, and 36% essential oil performance, respectively. As a result, the F. mosseae was identified as a beneficial stimulator to reduce the damage caused by heavy metal stress.
