BIOACCUMULATION OF SODIUM FLUORIDE TOXICITY IN TRITICUM AESTIVUM VAR. RAJ. 3077

A study of fluoride (F) accumulation in Triticum aestivum (Wheat) var. Raj 3077 and its effect on the growth and crop yield was conducted in Pot experiment. Eight different concentrations of Flouride in the water were used for irrigation ranging from 3 to 21 ppm with distilled water as the control. Potentiometric determinations of the Fluoride content in different parts of the plant were made after sowing the seeds (Pre, Peak and post harvest, respectively). At the post harvest the highest mean concentrations of fluoride were recorded with 21 ppm in the irrigation water 20.64 mg/kg in the leaves, 16.69 mg/kg in the stem, 15.28 mg/kg in the roots and 10.65 mg/kg in the crop (seeds).
