title: [Antagonism in the action of kinetin and actinomycin D on the cytogenetic effect of radiation].
abstract: A study was made of the effect of kinetin when administered separately or in combination with actinomycin D on the chromosomal aberrations in Crepis capillaris L. irradiated by X-rays. Dry seeds were treated after irradiation or seeds soaked, prior to irradiation. Significant decrease in the frequency of chromosomal aberrations was shown when actinomycin D was administered separately and prior to kinetin. The latter used separately and prior to actinomycin D slightly increased the level of the aberrations, as compared with the control. Noticeable radioprotective effect was observed after treatment of seeds with kinetin, prior to irradiation.
