Gamma irradiation is one of the physical mutagens that widely used for mutation breeding, food sterilisation and medicinal healing. In the present study, in vitro mutagenesis techniques were applied to investigate the effects of gamma irradiation at 0, 10, 20, 30, 40 and 50Gy on physiological changes in Citrus sinensis. Studies revealed that based on the(More)
Heavy ion beam, which has emerged as a new mutagen in the mutation breeding of crops and ornamental plants, is expected to result in the induction of novel mutations. This study investigates the morphological and biochemical responses of Oryza sativa toward different doses of carbon ion beam irradiation. In this study, the dry seeds of O. sativa were(More)
The radiosensitivity and cytogenic analysis of two Zingiber Officinale Roscoe varieties; Bentong and Tanjung Sepat were carried out using Caesium-137 as gamma ray source. Six different doses treatment were applied as follows: 0, 5, 7, 9, 11, 13 and 15 Gray. The LD50 (Lethal dose) value was determined based on the rhizomes survival rate. With attention to(More)
