Previous work had shown the presence of ''antimitotic'' substances in irradiated plants that could account for the cessation of cell division in the plant. An attempt was made to detect mutagenic activity on the part of these metabolites by irradiating 12 to 14 day plants of Vicia faba with an x-ray dose of 25,000 r. An extract was prepared from the irradiated plants, and 3 to 4 day rootlets of Vicia faba were placed in this extract for 24 hrs. The rootlet was fixed and stained in order to make an anaphase and telophase count, and a count of the chromosome aberrations (bridges) and of micronuclei. Rootlets grown in water and in an extract of unirradiated plants served as controls. The percent of chromosome aberrations based on the number of anaphases and telophases observed was 5.3% for the plants grown in the irradiated extract compared to 1.1% for the controls. Thus, it is concluded that there is a stable material formed during irradiation that possesses mutagenic activity. (TTT)
