The composition of free amino acids was studied from leaves, pericarps, skins, musts and seeds of Vitis vinifera L. cv. Cabernet Sauvignon. Vineyards were in the Bordeaux region and the grapevines were conducted in espalier and lyre systems. Grapes w

L'évolution, dans les baies de raisin, de l'acide abscissique libre (ABA) et de sa forme conjuguée, l'abscissate de β-D-glucopyranose (ABA-GE), est maintenant bien connue (BROQUEDIS, 1987). On sait notamment qu'une forte accumulation de ce régula

The subject of this study is the development of medium size shot berries of Vitis vinifera. At the time of vintage, their size reaches 4-7 mm. Their cell structure development is compared stage by stage with that of normal berries. On the same cluste

Some hypodermal cells of grape berry become pulp cells during growth stage to maturity. Their vacuolar tannins disappear and their cell walls get thinner in two times. In a first time, cell walls lose their polysaccharides (PAS negative walls), then

Structural and ultrastructural investigations on plastidial ontogenesis in the tissues of Vitis vinifera berry arc realised in narrow association with starch and chlorophyll dosages from the stage of fruit setting till berry ripeness. During the whol

Gynaecium ontogenesis of Vitis vinifera L. var. Chardonnay is followed up stage by stage. It is divided into twenty stages from initial meristem at the top of pedicel till just after the fruit is set. Each stage is morphologically and cytologically i

On attribue aux polyamines un rôle dans l'adaptation des plantes à différents stress. Peut être parce qu'elles ont la possibilité de capter des ions H+ pour donner des polycations (-NH3+), contribuant ainsi à la régulation du pH des cellules.

L'étude des polyamines (PA) et de l'acide abscissique (ABA) dans les bourgeons latents a été faite à différentes étapes de la multiplication de la vigne par greffage. Elle a permis de mettre en évidence les évolutions inverses de l'ABA libre
