• In the moss Physcomitrium sphaericum, we examined the number of buds per filament, the position of buds, and the ratio of bud-differentiated filaments when treated with cytokinin, in relation to the increase in the number of cells per filament. When filaments of a young protonema were treated with cytokinin, many filaments did not differentiate buds. As the number of cells in a filament increased, both the mean number of buds per filament and the ratio of bud-differentiated filaments increased. However, the position of bud differentiation was unaffected by application of cytokinin. A higher concentration of cytokinin increased the mean number of buds per filament and the ratio of bud-differentiated filaments. The relationship between cytokinin, ageing of filaments and the ability to differentiate buds is discussed.
