Onion Root

Seeds of Allium cepa were grown in complete darkness at constant temperature. The root tips, collected from hours 72 to 96 after the start of imbibition, exhibited four maxima and four minima in mitotic activity. The timing of this rhythm was dependent upon the time of imbibition and not upon the time of day.
