“…I have reported [50] on a trial of pruning date on Merlot in Bordeaux. There was an ill-ascertained trend in that direction, while Ravaz [47] in a very well conducted trial on Aramon, and Bouard [13] on Ugni blanc, both had observed clear-cut results in favour of a favourable effect of late pruning. From a trial using Mullins' [40] technique of defoliation on one-bud cuttings, I could demonstrate the existence of a variation in sensitivity to endogenous cytokinins among various varieties, that may explain the discrepancies among these three trials.…”

International audienceWe present a series of three papers that aim at providing a synthesis of the information collected or obtained from 1956 to 1974 at the Station de Recherche de Viticulture INRA in Bordeaux. This work was continued and expanded along new avenues mainly by Carbonneau [CITE]. As it is, it endeavoured to study the relationships that prevail between traits which are easily assessed on the vine and are important in determining the production of a crop. It showed that to be meaningful, experimenting with factors that are expected to influence yield must last at least three years; it provided a simple and practical means to eliminate subjective influences from the experimenter on the trial by the use of pruning scales defining the load as a function of the weight of prunings; it showed for the first time how to study in isolation a single three-year cycle leading to the production of a crop.Vigueur, taille et production chez la vigne (Vitis vinifera L.). I. Synthèse bibliographique. Nous présentons une série de trois articles qui ont l'ambition de fournir une synthèse d'informations collectées ou obtenues de 1956 à 1974 à la Station de recherche de Viticulture INRA de Bordeaux. Ces travaux ont été continués et amplifiés depuis dans des voies nouvelles par Carbonneau [CITE]. Ils tendaient à étudier les relations entre les divers caractères qui sont facilement déterminés sur une plante de vigne et qui sont importants pour le déterminisme de la production d'une récolte. Ils ont montré que, pour avoir un sens, l'expérimentation sur des facteurs susceptibles d'avoir un effet sur le rendement doit durer au moins trois ans. Ils ont fourni des moyens simples et pratiques pour éliminer les influences subjectives de la part de l'expérimentateur en utilisant des échelles de taille définissant la charge en fonction du poids des bois enlevés à la taille. Ils ont montré pour la première fois comment étudier en isolement un seul cycle de production de trois ans

“…Growth retardants: Complete or partial cessation of vegetative growth favors flower initiation in many orchard species (62). Accordingly, chlormequat, a growth retardant, was used by several workers to reduce the vegetative growth and to induce flowering in grapes (42,49,81,117,164,172,174). Besides promoting inflorescence primordium formation in latent buds, chlormequat induced ~'secondary inflorescences" by transforming the tendrils of the primary shoot and lateral shoots into inflorescences (42,78,150,163).…”

Physiology of Flowering in the Grapevine — a Review

The vegetative and reproductive anatomy of the grapevine is discussed with emphasis on recent interpretations based on scanning electron microscopy. The terminology of flowering in Vitis is defined and a developmental code, comprising Stages 0 to 11, is proposed for the events leading to formation of flowers. In brief, flowering in the grapevine involves three main steps: 1) Formation of Anlagen or uncommitted primordia (Stages 0 to 1); 2) Differentiation of Anlagen to form inflorescence primordia (Stages 2 to 7); and 3) Differentiation of flowers (Stages 8 to 11). The literature on the factors that influence flowering in grapes is reviewed under three major headings: 1) Biochemical
