Abstract

In the majority of shoots on a grapevine the number of internodes is fairly constant at anthesis. The number of visible internodes was higher in Vitis vinifera L. (16-19) than in V. labruscana BAILEY (12-14). This synchrony in the rates of development of nodes at the shoot tip and of the flowers on the inflorescences was found in a wide array of conditions (time, cultivars, countries, climates, cultural practices). The factor found to cause greatest variation between vines was vine vigour.

La croissance des rameaux et l'anthese de la vigne

La majorité des rameaux verts de la vigne montre un nombre assez constant d'entrenoeuds au moment de l'anthèse. Vitis vinifera L. (16-19) présente un plus grand nombre d'entrenoeuds que V. labruscana BAILEY (12-14). On retrouve dans diverses conditions (années, variétés, pays, climats, pratiques culturales) cette synchronisation de la vitesse du développement des noeuds de l'apex végétatif avec celle des fleurs sur les inflorescences. La vigueur de la vigne elle-même est le facteur responsable des plus grandes variations dans le nombre d'entrenoeuds au moment de l'anthèse.
