Abstract: (7 Views)
Salinity is one of the major factors limiting agricultural production worldwide. Under salinity conditions, nutrient imbalances affect plant growth by disrupting nutrient uptake, transport, and distribution, leading to deficiencies or imbalances in nutrients. This experiment was conducted as a factorial design within a completely randomized structure (CRD) with three replications in 2021 to evaluate the effect of zinc nanoparticles on Physalis alkekengi L. under salinity stress. Four levels of salinity (control, 50, 100, and 200 mM) and four levels of zinc nanoparticles (control, 50, 100, and 200 mg/L) as foliar applications were tested. The results indicated that, compared to the control, the highest salinity level (200 mM) caused significant reductions in several characteristics: shoot fresh weight (30.44%), root fresh weight (23.57%), fruit weight (24.18%), fruit yield (67.26%), potassium content (30.52%), total phenol (4.14%), and vitamin C (11.36%). However, under 200 mM salinity, an increase was observed in soluble solids (8.4%), catalase activity (0.510 U/mg protein), superoxide dismutase (5.11 U/mg protein), and sodium content in leaves (7.72 mg). Zinc nanoparticles helped mitigate the adverse effects of salt stress, enhancing plant traits. The control treatment produced the highest fruit yield at 122.71 mg per plant. Based on the findings, zinc nanoparticle concentrations up to 100 mg/L improved the performance of Physalis alkekengi L., whereas higher concentrations did not have any additional effect on the measured traits.
