Determination of radio sensitivity of jasmine (Jasminum spp.) to gamma rays

Abstract

Present study was carried out to find out mutagenic sensitivity of jasmine species to gamma rays. In this study, terminal and semi hardwood cuttings of three different jasmine species (Jasminum grandiflorum, cv. White, Jasminum multiflorum cv. Arka, Arpan and Jaminum nitidum pre-release culture Acc.Jn-1) were subjected to eight different dosages of gamma radiation ranging between 5 Gy and 40 Gy. The results revealed a gradual and significant reduction in survival of cuttings, shoot length, number of leaves, leaf length and leaf width with increase in dosage of gamma rays. The probit curve analysis based on the survival percentage and growth rate of treated cuttings revealed that the LD50 dosages of gamma rays for cv. White, Arka Arpan and ACC Jn-1 were 17.8 Gy, 28 Gy and 25.1 Gy respectively.
