The effects of solutions of benzimidazole and 5-aminouracil onAllium cepa root meristems immersed in them have been studied cytologically. Benzimidazole and 5-aminouracil, analogues of purines and pyrimidines respectively, reduce the number of nuclear divisions being initiated. A marked decline in frequency of cells in mitosis occurs at the beginning of treatment with benzimidazole (300 p.p.m.) but not until 6 or more hours later with 5-aminouracil (125 p.p.m.). After treatment with 5… CONTINUE READING
