Growth and development of shoot apex in barley II. Distribution of growth rates during vegetative phase

Zygmunt Hejnowicz, Wiesław Włoch

Abstract


The changes in the volume of the apical dome and of the frusta indicate that the mean relative rate of volume growth of the whole apical dome is much higher than in the first frustum which, in turn, grows much faster than the next one. It was found in studies of the distribution of mitoses and of cell arrangement that the volume relative growth rate of the distal part of the apical dome is at least 5-10 times slower than that at the level of new leaf primordia initiation.
