Fluoride contamination in water, soil and plants is a serious health problem throughout the world. We studied the effect of aqueous solutions of 0, 10, 20, 30, 40 and 50 ppm sodium fluoride on seed germination, seedling growth and biochemical parameters of Abelmoschus esculentus. The experiment was conducted as factorial with completely randomized design with five replicates. The percentage of seed germination decreased up to 62 percent with increasing sodium fluoride treatment. The seedling growth parameters (root length, shoot length and vigor index) and biochemical parameters i.e., chlorophyll, nitrogen and protein content as well as the Fluoride uptake by the germinated seedlings were estimated after 20 days of treatment.
