Abstract:   (196 Views)
In order to investigate the effect of biochar and selenium on the quantitative and qualitative characteristics of coriander (Coriandrum sativum L.) under cadmium stress, a factorial experiment was conducted in the form of a completely randomized design with three replications in greenhouse conditions during the years 2022. The experimental treatments include the use of cadmium chloride at three levels (0, 10 and 20 mg/kg), biochar at two levels (0 and 5% of soil) and foliar spraying with sodium selenate at two levels (0 and 20 mg/l). The results of this research showed that cadmium treatment of 20 mg/kg caused a decrease in fresh and dry weight of shoot and root, chlorophyll a, b and total, relative leaf water content and increased activity of superoxide dismutase enzyme and soluble sugar. Phenol increased up to the cadmium level of 10 mg/kg, but decreased at higher cadmium levels (20 mg/kg). By reducing the effect of cadmium stress, selenium and biochar treatments increased the fresh and dry weight of roots and shoots, chlorophyll content, relative leaf water content, and essential oil yield, and decreased the characteristics of superoxide dismutase enzyme activity, soluble sugar, and cadmium accumulation in roots and shoots. The highest amount of essential oil yield (16.93 mg/plant) and percentage of essential oil (0.44%) was observed in the combination treatment of biochar 5% by volume and selenium 20 mg/l. Biochar and selenium improved coriander traits by modulating the effect of cadmium stress.
