Effect of gamma rays and ems on yield parameters in Hibiscus sabdariffa
Author(s): MS Shukla, KG Dube
Abstract: Dry seeds of Hibiscus Sabdariffa (Family - Malvaceae) were irradiated with Gamma rays at 10 to 60 KR. Presoaked seeds (6 to 18 hrs.) were treated with 0.1 to 0.5 % EMS & for combination treatments, irradiated seeds were immersed in 0.2 % EMS. Observations on the yield parameters were recorded. It was observed that in the dose of gamma rays or concentration of EMS in alone or gamma rays followed by EMS in combination treatments showed minimum days for flowering & fruiting while maximum days required for flowering & fruiting were recorded at higher doses. The lower exposures of mutagenes showed maximum number of flowers, fruits, seeds & weight of seeds while drastic reduction was observed at higher doses.
