This study systematically investigates the physiological responses of Physalis alkekengi to diverse conditions of salinity stress (0, 50, 100, and 200 mM NaCl), coupled with the application of selenium (Se) nanoparticles at concentrations of 25 and 50 mgl-1, as well as silicon (Si) nanoparticles at concentrations of 100 and 200 mg.l-1. The experiment involved a thorough examination of many characteristics connected to biomass, such as antioxidant enzyme activity, fatty acid composition, and elemental content. This analysis was conducted at varying levels of salinity and with the addition of nanoparticles. The findings revealed that exposure to salt stress has a detrimental effect on both plant development and fruit output, leading to changes in vegetative and morphological characteristics. The utilization of Se and Si nanoparticles had a significant alleviating impact on stress caused by salinity. The correlation matrix analysis revealed complex correlations among the examined parameters, emphasizing the interrelated responses of P. alkekengi to environmental stressors and nanoparticle interventions. Principal Component Analysis (PCA) revealed the hidden patterns and connections between variables, highlighting the significant influence of biomass-related features, antioxidant enzymes, and fatty acid content on the observed variability. The results of this study enhance our knowledge of the physiological processes that regulate P. alkekengi's reaction to high salt levels. Additionally, it offers valuable information on the possible beneficial impacts of Se and Si nanoparticles in reducing the negative consequences of salinity stress. The study's comprehensive breadth increases its relevance to future research focused on optimizing growth circumstances and strengthening the resistance of P. alkekengi in demanding situations.
