The field investigation entitled “Seed Germination of Pummelo (Citrus grandis L. Osbeck) as affected by storage period and presowing treatments” was conducted at experimental farm, department of Horticulture, College of Agriculture, Dapoli, Dist. Ratnagiri (M.S.) during the year 2012-2013. From the investigation, it could be concluded that freshly harvested pummelo seeds had shown better results in per cent seed germination and growth parameters of pummelo seedlings up to six month of sowing. Among different pre-sowing seed treatments studied; soaking of seeds in GA3 50 ppm for 24 hrs recorded better effect on per cent seed germination and most of the growth parameters and it was followed by scalding at 500C for 24 hrs. In interaction effect, soaking of freshly harvested pummelo seeds in GA3 50 ppm for 24 hrs had shown better results in terms of per cent seed germination as well as most of the growth parameters to achieve vigour of pummelo seedlings up to 6 months after sowing and was followed by scalding of freshly harvested pummelo seeds at 500C for 24 hrs.
