Growth regulators in changing apical growth at transition to flowering
- 1 Institute of Experimental Botany, Czechoslovak Academy of Sciences, Praha 6, Czechoslovakia
Reorganization of growth in the shoot apex ofChenopodium rubrum during transition to flowering is described. Growth and morphogenic changes - a rise in cell division rate, changes in leaf and bud formation and changes in directions of cellular growth - are viewed from the aspect of a possible role of growth hormones in controlling these changes. Growth and morphogenic effects of exogenous growth regulators in the shoot apex ofChenopodium are summarized and their floral effects explained in terms of changing apical growth correlations. New evidence concerning the timing of increased cell division rate and showing the limited requirement of axillary cell division and a shift to more vertical direction of growth in the apex in the floral developmental pathway was obtained in experiments with kinetin application and by surgical treatments.
