Chromosome Damage and Growth Reduction Produced in Roots of Vicia Faba by X-rays and by Triethylene Melamine

Abstract
If groups of broad-bean roots are treated with X-rays or by immersion in triethylene melamine solution, and if the doses are adjusted so that the subsequent reduction in growth is equal, then the cells of the root-tips carry equal numbers of chromosome aberrations. This had previously been shown when X-rays and 8-ethoxycaffeine were compared.
