RATES OF MITOSIS IN A PARTIALLY SYNCHRONOUS MERISTEM

摘要: Summary In root apices of Sinapis alba mitosis is partially synchronous under certain cultural conditions, with two maxima and minima mitotic index each day. But the phase partial synchrony different in stele cortex from that cap initials quiescent centre. The average rates vary once 35 hours to 500 Cells divide more slowly near centre than at 150 microns it. In this respect differs Zea dissimilarity organization may be due possession opportunity it gives for phasic differences synthesis.
