Effect of Concentration of Seed Hardening Chemicals on Physiological Characters of Pearl Millet (Pennisetum typhoides Stapf and Hubb)

A laboratory study was taken up in the Department of Agronomy, Tamil Nadu Agricultural University, Coimbatore in the year 1986 to fix optimum concentration and to evaluate the efficiency of CCC (2-chloroethyl trimethyl ammonium chloride), succinic acid and sodium chloride as seed hardening chemicals for pearl millet. The study revealed that CCC 100 ppm, succinic acid 0.15 per cent and sodium chloride 1 per cent concentrations were better in improving the germination per cent, root : shoot ratio and vigour index of pearl millet.
