Study of physiology of seedlings and plants under fluoride toxicity is of recent origin, adding one more factor in the environmental stress. The toxicity of fluoride affects the yield of agricultural crops. Fluoride contamination in water, soil and plants has been a continuing problem in the world. The present study was made to assess the effect of fluoride on especially in germination of seeds. In this investigation, the effects of NaF, MgCl2 and NaF+MgCl2 on seedling growth of Alfalfa plants (Medicago sativa. L.) and physiological parameters viz., root length, shoot length, seedling growth, dry weight and moisture were studied. After observation fluoride effect on Medicago sativa root length and shoot length increased in all media. Seedling growth besides the root and shoot elongation is the fresh weight is increased and dry weight gradually decreased in all media. The initial uptake of water by NaF seedling is less, later on as the germination proceeds, it was higher or less equal to other seedling by adjusting internal osmotic balance. It is known that Na increases to cause succulence.
