Abstract: (27 Views)
To assess the influence of selenium on the growth and production of Persian shallot under drought stress conditions, a factorial experiment was conducted utilizing a randomized complete block design with four replications at the Shahrekord University Research Farm in 2023-2024. The experimental factors included levels of drought stress (absence of stress and presence of drought stress) and foliar application of selenium (0, 3, 6, 9, and 12 mg/L). The results indicated that drought stress significantly impacted plant height, the number and fresh weight of leaves, root fresh weight, the number and weight of sisal bulbs, bulb fresh weight, relative leaf water content, membrane electrolyte leakage, proline and leaf soluble protein levels, malondialdehyde, hydrogen peroxide, and photosynthetic pigments. Selenium exhibited a significant effect on the aforementioned traits except for carotenoids. The interaction between selenium and drought stress was significant for leaf fresh weight, root fresh weight, bulb weight, relative leaf water content, membrane electrolyte leakage, proline and leaf soluble protein levels, malondialdehyde, and hydrogen peroxide. Under drought stress conditions, the application of foliar selenium at a concentration of 3 mg/L selenium led to an increase of 10%, 154%, 11%, and 121% in leaf fresh weight, bulb weight, relative leaf water content, and proline levels, respectively, compared to the treatment without selenium treatment. The greatest and least bulb fresh weights (65.4 and 48.9 g/plant) were recorded with foliar application of 3 and 12 mg/L selenium, respectively. Overall, it can be concluded that the foliar spraying of selenium at a concentration of 3 mg/L enhances the drought tolerance of Persian shallot plants and augments metabolic and biochemical activities associated with plant growth, thereby aiding in the preservation of its production capacity.
