Relationship between the Growth Rate of a Filament and the Ability to Differentiate a Bud in the Moss, Physcomitrium sphaericum

Protonemata filaments of the moss Physcomitrium sphaericum display growth rates that change remarkably before they differentiate buds under normal conditions, that is, without cytokinin treatment. Before bud differentiation occurred, the growth rate of the filament first decreased to a minimum and then increased to a maximum and decreased again. Study of whether the change in the growth rate is related to bud differentiation showed that bud differentiation was closely related to the maximum growth rate and the fluctuation range, that is, the difference between the minimum and the succeeding maximum growth rate. The frequency of bud-differentiated filaments increased as both the maximum growth rate and the fluctuation range of growth rate increased. Examination of the relationship between the time of cytokinin application and the frequency of bud-differentiated filaments showed that the cytokinin treatment given at the time when the growth rate increased was most effective to induce buds. The relationships between cytokinin, growth rate of filaments and the ability to differentiate buds are discussed.
