Fluorine element occurs naturally. It is not considered as an essential element for growth of plants. Consumption of high amount of fluoride can cause toxic effects in plant and animals. Fluoride effect creates unbalancing in up-taking of other nutrients also. High concentration of fluoride shows phytotoxic effect on morphological and biochemical properties of plants. Fluoride acts as an inhibitor for the metabolic activities occurring during the seed germination process. Plant protein content also declines in the presence of high levels of fluoride. Current study shows fluoride toxicity effects on physiological and biochemical consequences during seedling growth in Vigna radiata
