Circadian rhythms clearly affect cell division in certain microorganisms and some animal tissues, but reports on mitotic rhythmicity in higher plants are contradictory, even for Allium cepa, the most widely studied material. Mitotic index was determined on root and shoot meristems of seedlings of one cultivar, and on roots of bulbs of another. Various times with respect to 24-h cycles of alternating light and darkness, or light-high temperature and darkness-low temperature were investigated. No evidence for rhythmicity was obtained.
