Translocation of growth regulators from roots in relation to the stem apical dominance in pea (Pisum sativum L.) seedlings

Since it has been found that roots are a source of cytokinins [2], [8] and gibberellins [1,7] and that exogenous applications of cytokinins and gibberellins can promote bud growth [5], [9] several authors have studied the relationships between the transport of growth regulators from roots and the development of lateral buds [3]. The role of growth regulators synthetized in roots and translocated into the above-ground part of plants in relation to the apical dominance of the stem has not yet been completely explained. The condition of a bud releasing itself from a correlative inhibition is changing very quickly and involves two stages, viz. (a) the release from the correlative inhibition and (b) the subsequent growth of the lateral bud [6].
