| چکیده فارسی مقاله |
Basil plants are highly sensitive to environmental stresses, which can negatively impact their growth and productivity. In order to explore whether 24-epiBL seed priming could alleviate the adverse effects of cadmium (Cd) and water stress on basil, an experiment was conducted in the greenhouse with a completely randomized design in three replications. The basil seeds were primed with two concentrations of 24-epiBL (0 and 10-2μM). Plants were treated with three levels of watering regimes consisting of 100% field capacity (FC) as control (no stress), 50% of FC (moderate stress), and 25% of FC (severe stress). The Cd stress was applied at concentrations of 0, 10, 20, and 30 mM every two days. Results indicate that upon severe water and 30 mM of Cd stresses, chlorophyll a, b, and carotenoid declined by 33, 26, and 20% compared to the control condition. The hydrogen peroxide (H2O2), malondialdehyde (MDA), Cd, proline, and soluble sugar contents were raised at severe water and Cd stresses by 130%, 42%, 580%, 41%, and 33% in comparison to the non-stressed control plants. However, the pre-treated 24-epiBL plants, subjected to combined severe water and Cd stresses, displayed an increment in chlorophyll a (50%), b (26%), carotenoid (53%), H2O2 (160%), and proline (82%) contents with a decrement in MDA (16%), Cd (346%), and soluble sugar (25%) contents compared to non-primed basil plants under severe water and Cd stresses. These findings suggest that 24-epiBL seed priming can be a promising strategy for enhancing basil's resilience against environmental stresses, which ultimately contributes to improved crop productivity and sustainability. |
