Gamma Rays and EMS Induced Morphological Parameters in Hibiscus Sabdariffa
M. S. Shukla | K. G. Dube [2]
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 morphological parameters were recorded after One, Two & Three months. The lower exposures of gamma rays reduced plant height, number of leaves and area of leaf to smaller extent while drastic reduction was observed with higher doses. EMS in alone treatments induced reduction in all these parameters with the corresponding increase in the duration of presoaking & concentration of EMS. In case of combination treatments all these parameters showed gradual decrease with the corresponding increase in the dose of gamma rays followed by EMS concentration. The present paper deals with the results of these experiments.
