Studies on the impact of fluoride toxicity on growth parameters of Raphanus sativus L.

A study was concluded during 2011 2013 on the effect of various concentrations 50, 100, 200 and 400 mg NaF/kg soil on different growth parameters in Raphanus sativus L. Different concentrations of sodium fluoride inhibited seedling germination percentage, length of root, length of shoot, plant height, number of leaves, size of leaf, number of flowers per plant, fruit-set percentage and seed-set percentage. The plants growth in soil supplemented with 400 mg NaF/kg soil shows maximum reduction in their growth parameters as compared to control plants.
