Abstract

The somatic cell cycle time (T) was measured by tritiated thymidine autoradiography in root-tip meristem cells of two barley varieties. In a spring variety, Sultan, T was 12.4 h and this did not differ significantly from the T of 12.0 h in Maris Otter, a winter variety. These estimates are in good agreement with previous measurements of cell cycle time made for other cereal species. As in other cereal species, the duration of the division stages during mitosis in barley are much shorter than the durations of the corresponding stages of meiosis.
