Abstract
During the 2021 and 2022 growing seasons, this study was conducted at the nursery of the Department of Flowers, Ornamental Plants, and Landscape Gardens, Faculty of Agriculture (El-Shatby), Alexandria University, Alexandria, Egypt. The purpose of the study was to determine whether lead phytoremediation could be accomplished by spraying Gazania rigens plants with citric acid. And effect of on the vegetative growth and chemical makeup of Gazania rigens plants, Used four levels of lead in irrigation water (0 - 100 - 200 - 300 mg/l) and three concentrations of citric acid (0 - 250 - 500 mg/l) sprayed on leaves and the interaction between them on vegetative growth, chemical content of Gazanis plants, and soil content were studied. From lead after cultivation. The results showed a considerable difference between lead concentrations and foliar citric acid spray for vegetative growth metrics. While all parameters significantly decreased following irrigation with water containing lead, vegetative growth parameters significantly improved with the application of 500 mg/l citric acid. The highest significant amounts of lead content in leaves and roots were found in plants treated with 300 mg/l lead without the application of citric acid, whereas the highest significant amounts of chlorophyll and carbohydrates were found in plants irrigated with tap water and sprayed without citric acid. A higher lead concentration in the soil after planting was also generated by the combination of 500 mg/l citric acid and 300 mg/l lead.
