Zusammenfassung: The investigations we have undertaken to test the influence of potassium cyanate on the roots of bulbs of Allium cepa L., have shown: 1. Cyanates have a remarkable antimitotic action on the roots of bulbs of Allium cepa L.; this action was apparent in the tests which we carried out with potassium cyanate solutions of a higher concentration than the marginal one of 0.00125 %.2. Cytological tests, carried out on radical apices of bulbs immersed in cyanate solutions of various concentrations, proved that the power to inhibit the ingress in mitosis of interkinetical nuclei, intrudes particularly on the physiological processes of the preprophase.3. The preprophasical inhibition that cyanates exercise on the roots of bulbs of Allium cepa L. is in accord with the retarding action of cyanates on the enzymes containing cytochrome, such as, for instance, the catalases which act in the particular period of the preprophasical process.
