Grapevine nitrogen status was assessed by nitrogen content in leaf blade and petiole at veraison, in must at harvest and in pruned wood in December. The comparison of these indicators were done in vineyards bearing adults plants in the Atlantic and M

Five indicators of vine nitrogen status were compared for their accuracy to differentiate two levels of nitrogen fertilization (0 and 45 kg N / ha) : petiole total nitrogen content, leaf blade color intensity measured by a device called “N-tester

The study was carried out in order to compare the development of berries growing on fruiting cuttings and on vines from the field, and to evaIuate this experimentaI system for grapevine physiology studies. The results show that the main developmental

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.
