[The rhythms of daily mitotic activity in Vigna radiata (L.) R. Wilczek]
Abstract:
The daily mitotic activity (MA) in Vigna radiata (L.) R. Wilczek. has been studied using local cultivar for Vietnam No I 176. It has been shown that the curve of mitotic activity has five peaks. Maximum mitotic index (MI) was observed at 04:00 (5.93 %) and the other peaks were at 02:00 (5.58 %), 08:00 (4.70 %), 12:00 (4.60 %) and at 22:00 (4.60 %). If we took into account that duration of the mitotic cycle in Vigna radiata makes up ten hours, we can propose that there are two peaks of MA within each cycle. It may be due to the presence of two meristematic cell subpopulations which enter mitosis at different time and have nearly equal duration of the cell cycle.
