Abstract

                                Nine month old seeds of sunflower cv. Morden were soaked in different chemicals viz., ferrous sulphate, borax, cobaltous chloride, ammonium molybdate, potassium dihydrogen orthophosphate and calcium chloride at different concentrations as well as at different seed to solution ratio. The treated seeds after drying to their original moisture content were evaluated for germination and vigour. The results showed that seeds soaked in one per cent calcium chloride solution for 6h in 1:1 seed to solution ratio improved the germination by 18 per cent with increased vigour over control.

Key words : Sunflower seeds, chemicals, germination, vigour
