Abstract
This study investigated the influence of various nanoparticles (NPs), including carbon-based NPs, Al 2O 3-NPs, SiO 2-NPs, and TiO 2-NPs, on the growth and physiology of okra plants cultivated in soil impacted by rocky desertification. The morphological characteristics, photosynthetic parameters, antioxidant capacity, nutrient uptake of the okra plants, and available nutrient content in the soil were evaluated. The results demonstrated a significant improvement in the growth, photosynthetic properties, chlorophyll content, and activities of antioxidant enzymes (catalase, peroxidase, and superoxide dismutase) in the okra plants treated with NPs compared to the control. Additionally, the NP-treated plants exhibited enhanced total nitrogen content, and hydrolysis nitrogen content in soil was also significantly increased, indicating improved nitrogen uptake. Notably, TiO 2-NPs demonstrated the most pronounced effects on plant growth and photosynthetic characteristics, while TiO 2-NPs and SiO 2-NPs showed higher antioxidant enhancement compared to other NPs. These findings suggest the potential of nanoparticles as a promising agricultural solution to address challenges in regions like Guizhou Province, China.
