Changes in cell number, cell size, fresh weight, and dry weight were recorded for the growth cycle of a serially subcultured cell suspension culture derived from hypocotyl of bush bean (var. Contender). The various cell types and growth patterns from single cells were also recorded. The culture showed unique features including a relatively sharp separation of a phase of exponential cell division from a phase of cell expansion. Complete separation of cell clumps gave a free cell culture, of viable cells, by day 16. The growth cycle, cell types, and growth patterns are compared with those in other plant cell suspension cultures. The potential value of the culture for study of growth regulation is discussed.
