Abstract: (78 Views)
In order to evaluate the inoculation of mycorrhizal and growth-promoting bacteria (Pseudomonas genus) on the tolerance of European borage to cadmium toxicity, a factorial experiment was performed in the form of a completely randomized design with 3 replications in the research greenhouse of the Agriculture Faculty of Yasouj University in 2019. The experimental factors include the application of biological fertilizer at 4 levels (control, application of mycorrhiza, application of growth-stimulating bacteria and combined application of mycorrhiza and bacteria) and 4 levels of cadmium concentration (0, 25, 50 and 75 mg cadmium per kg soil). The investigated traits were included root colonization percentage, plant cadmium content, some physiological characteristics and shoot dry weight of European borage. The results showed that with the increase in cadmium concentration, electrolyte leakage, proline content and cadmium content of aerial organs increased. The use of mycorrhiza and bacteria was evaluated positively compared to their non-use, so that in all four levels of cadmium, the highest proline, chlorophyll and relative water content, as well as the lowest electrolyte leakage and shoot cadmium concentration, were obtained from the combined two biofertilizers. Application of biofertilizer increased the dry weight of the aerial parts of inoculated plants compared to the control. The results showed that in the presence of 25 and 50 mg/kg of cadmium, the combined application of bio-fertilizers reduced 21% and 17% of cadmium transfer from roots to shoots of borage. Therefore, it is recommended to use biological fertilizers in areas contaminated with cadmium.
