[Effect of gamma radiation on organs and cells of higher plants cultivated in vitro. Dose effect on survival of axillary buds of haploid and diploid Nicotiana sylvestris and Nicotiana tabacum].
The Dose/Action relationship between gamma irradiation and bud survival, plotted on log-linear axes, produces a plateau (no decrease in survival) followed by a straight line decrease. The length of the plateau and the slope of the line appear to depend on the degree of ploïdy and the structure of the genome. There could be redondant parts in the genome of Nicotiana sylvestris.
