This study investigates the synergistic effects of zinc oxide nanoparticles (ZnO NPs) and melatonin (MT) on Fragaria × ananassa (strawberry) plants under drought stress, focusing growth, fruit biomass, stress tolerance. ZnO NPs enhance nutrient uptake resistance, while MT regulates growth hormones boosts photosynthetic efficiency. Seven treatments were evaluated: T1 (no 0.5 g/L + 0.1 MT), T2 NPs), T3 T4 (drought no application), T5 T6 T7 MT). Growth parameters included shoot/root length, bud number, chlorophyll content, oxidative markers (H₂O₂, MDA), antioxidant enzyme activities in leaves ananassa. The combined treatment MT) consistently outperformed others, achieving highest metrics both conditions: shoot length (22.33 ± 1.53 cm non-stress, 15.00 drought), root (18.67 12.00 biomass (9.55 0.31 g 5.02 0.23 drought). Bud formation peaked at 3.33 0.58 buds/plant non-stress 2.00 0.00 drought. Under drought, also enhanced content (2.47 0.20 mg/g FW) significantly reduced H₂O₂ (28.67 2.52 µmol/g MDA (4.21 0.10 levels, maximizing (SOD: 121.67 7.64 U/g FW, POD: 206.33 14.84 CAT: 48.00 3.61 FW). These findings highlight application as a promising strategy to tolerance strawberry plants, warranting further research optimized concentrations, delivery methods, molecular mechanisms.

ABSTRACT Iron (Fe) deficiency is a critical constraint on global food security, particularly affecting high‐value horticultural crops such as strawberries ( Fragaria × ananassa ). This study examines the roles of melatonin and hydrogen sulfide (H 2 S) signaling in mitigating Fe stress by improving bioavailability enhancing plant resilience. Strawberry plants were cultivated under Fe‐sufficient Fe‐deficient conditions treated with 100 μM 3 mM dl‐propargylglycine (PAG), an inhibitor L‐cysteine desulfhydrase (L‐DES), which regulates H S production. significantly reduced chlorophyll content photosynthetic efficiency while elevating oxidative markers peroxide O ), malondialdehyde (MDA), electrolyte leakage (EL). Melatonin application alleviated effects utilization, stimulating L‐DES activity, promoting also improved antioxidant defenses boosting activities superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), well maintaining ascorbate‐glutathione (AsA‐GSH) redox dynamics. The addition PAG inhibited resulting levels diminished melatonin‐induced benefits, underscoring essential role L‐DES‐mediated synthesis. Despite presence PAG, co‐application 0.2 sodium hydrosulfide (NaHS) restored bioavailability, growth, capacity, suggesting synergistic interaction between S. highlights potential to improve homeostasis mitigate plants. findings offer strategies enhance crop resilience productivity nutrient‐deficient soils, thereby sustainable agriculture security.
