Auxin - Gibberellin Interaction in Apical Dominance " 2
Indoleacetic acid and gibberellic acid were added to decapitated lightgrown 'Alaska' pea seedlings as substitutes for the intact apex in the control of apical dotiinance. Of various concentrations and combinations tried, a conrbintation of 1 % indoleacetic acid 1 % gibberellic acid was the most inihibiting to side bud growth. The greatest degree of hormonally induced side bud inhibition was ach...

متن کاملApical dominance models can generate basipetal patterns of bud activation
An important aspect of plant development is the order in which lateral buds are activated to produce branches. This order may manifest itself, for example, in the gradient of branch lengths, or in the flowering sequence. One progression type is acropetal, with the lateral buds activated from the bottom up. Other plants exhibit a basipetal sequence of bud activation, with a downward progression ...
متن کاملIs ABA the earliest upstream inhibitor of apical dominance?
Axillary bud growth – and specifically its release from apical dominance – has been a longstanding and complex area of research. Many phytohormone systems, as well as sugar signaling, have been implicated. Now, Holalu and Finlayson (see pages 943–952) have found compelling evidence that a much less-studied hormone in this context – abscisic acid (ABA) – may, in fact, be one of the first upstrea...
متن کاملCytokinin is required for escape but not release from auxin mediated apical dominance
Auxin produced by an active primary shoot apex is transported down the main stem and inhibits the growth of the axillary buds below it, contributing to apical dominance. Here we use Arabidopsis thaliana cytokinin (CK) biosynthetic and signalling mutants to probe the role of CK in this process. It is well established that bud outgrowth is promoted by CK, and that CK synthesis is inhibited by aux...
