Radiosensitivity Study for Identifying the Lethal Dose in MR219 (Oryza sativa L. spp. Indica cv. MR219)
The purpose of the research was determine the effects of gamma ray on seed germination, seedling height and root length of Rice (Oryza sativa L. spp. Indica cv. MR219) to identify the Lethal Dosage of the radiation. Paddy seeds of MR219 were exposed to different doses of gamma radiations viz 50,100,150,200,250,300,350,400,450,500,600,700,800,900 and 1000 Gy using 60Co as the radiation source. T...

متن کاملEthyl Methane Sulphonate Induced Desynaptic Variants in Ajwain (Trachyspermum ammi (L.) Sprague)
Synaptic mutants are the subject of a special concern to cytologists and geneticists as they hold the variability in their recombination pattern. Seeds of Trachyspermum ammi (L.) Sprague (ajwain) were treated with Ethyl Methane Sulphonate (EMS) solution at 3 different concentrations viz. 0.1%, 0.3% and 0.5% for 5 h, prepared in potassium phosphate buffer with 7.0 pH. During meiotic observation ...
متن کاملEthyl Methanesulfonate (EMS)-Mediated Mutagenesis of Cucumber (Cucumis sativus L.)
Ethyl methanesulfonate (EMS) is a stable and effective chemical mutagen. In this study, cucumber (Cucumis sativus L. cv. “Shannong No. 5”) seeds were treated by 1% EMS for 12 h, 24 h and 48 h to optimize EMS mutagenesis and determined median lethal dose of EMS (1% EMS and 24 h) for “Shannong No. 5”. After treated by 1% EMS for 24 h, 541 M1 plants were grown in greenhouse for phenotype investiga...
