In grapevines, the young leaves play an important role in the control of the growth of anticipated buds. Through a basipetal inhibition, which these young leaves exercise over subjacent buds, they contribute to apical dominance. This inhibitory influence persists as long as the duration of laminar growth of the leaf; it is neither sector-based nor cumulative; it is perceived even by buds very far from young leaves. This foliar inhibition is also one of the causes of the acrotonic character of lateral ramification that develops, in the apical part of the shoot, after shoot tip removal. In the older part of the shoot, this acrotony, consecutive to a shoot section, is mainly determined by correlations between the buds. All these results are analysed and discussed in regard to morphogenesis elements previously established in other species. The contribution of young leaves to apical dominance has been demonstrated previously in many other plants. On the other hand, in grapevine, this morphogenetic character was unknown. The fact that young leaves contribute to the acrotonic development of the lateral ramifications growing after decapitation of the main shoot constitutes a much more original result because it has rarely been described in previous studies relative to other species. Earlier works also lead us to expect that both correlative inhibitions and competitive process are involved in the correlations between anticipated buds released from apical dominance. Concerning the growth correlations between grapevine buds, only thuse correlations relative to latent buds had been, until now, very much studied. New and precise knowledge on correlations that control the development of anticipated buds are supplied by this work. It appears then that correlations between these two sorts of buds have two common features: inhibition of their growth by young leaves and sectorial character of the inhibitions between the buds. A hypothesis on the mechanisms through which young leaves control the growth of anticipated buds is suggested. These mechanisms probably change in relation with the developmental stage of a bud; before the bud develops, the young leaves exercise on it a basipetal polarized inhibition. As soon as the bud begins to grow, nonpolarized competitive relations become established between the lateral ramification and the upper young leaves.Key words:Vitis vinifera, apical dominance, acrotony, leaves, buds, correlations.
