摘要： Purpose Fluoride (F-) pollution is one of the most serious issue facing the soil, water and agroclimatic variables as it does not occur naturally in its state but have always been found as the reactive substance in the earth's crust. It is always present in organic and inorganic forms, i.e., cryolite, fluorspar,and apatite,which is released into the atmosphere by brick kilns, fertilizers manufacturing factories,and other industrial industries. Methods The present study assessedthe impact of F(- )on growth, photosynthetic performance, and physiology of Withania somnifera L. plants. Results Results presented that high dose of F-(200 ppm) significantly affects the plant growth in terms of root, shoot length, and dry weight and exhibited approx. two-fold reduction in root length and shoot (22.65%) as evident by shortened internode and leaf number of W.somnifera L.The physiological characteristics viz., vapor pressure deficit (VPD), water-use efficiency (WUE), transpirationrate (E), and stomatal conductance (gs) also showed alterations in F(- )treated W.somnifera L. plants. Further, decreased soil plant analysis development (SPAD)valuesand photosynthetic pigments such as chlorophyll a, b,and a+b (12-43%) expressed toxicity response of F-. Conclusions The study demonstrates a negative impact of F(- )on growth, physiology, and medicinal value (metabolite content). Therefore, ecophysiological studies are prerequisites to the large-scale cultivation of W.somnifera L. plants for large-scale production.
