Abstract: (10 Views)
Cold stress is a significant factor that limits agricultural production. Cucumber, a crop that thrives in warm regions, is often grown in the autumn and winter but can be suddenly exposed to cold stress. Recently, Iranian farmers have faced considerable losses due to cold damage to their cucumber crops. This research investigated the effects of pretreating cucumber plants with selenium nanoparticles (SeNP) to enhance their resistance to cold stress. In the experiment, cucumbers were sprayed with SeNP solutions at concentrations of 0.2, 0.5, and 1 mg L⁻¹ during the three to four leaf stages. The findings revealed that under cold stress, the chlorophyll content decreased, while the activity of antioxidant enzymes, malondialdehyde content, hydrogen peroxide levels, phenolic compounds, proline, and soluble carbohydrates all significantly increased. However, pretreating the plants with SeNP effectively reduced the amounts of malondialdehyde and hydrogen peroxide, helped preserve chlorophyll content, and enhanced the levels of proline, soluble sugars, phenolic compounds, and antioxidant enzyme activity when compared to plants that were not treated with selenium. These results highlight the beneficial role of selenium as an active antioxidant in mitigating cold stress damage.
