Abstract

The aims are to evaluate morpho-anatomical bud development during dormancy and to compare the heat requirement needed to start bud break in several grapevine cultivars characterised by different geographic origins. A detailed description is presented of the bud growth stages of Vitis vinifera cultivars to contribute to the standardisation of national and international testing systems of fruit growing. Based on the general BBCH-scale, the codes describe the first stages of budbreak in several cultivars with different geographical origins. Dormancy release was evaluated both under natural and forcing conditions, appropriate method to establish the budbreak of deciduous species. The cultivars were characterised in relation to the achievement of complete bud scale opening stage (03 of BBCH scale) which is suggested to consider as an early and indicator of budbreak.The aims are to evaluate morpho-anatomical bud development during dormancy and to compare the heat requirement needed to start bud break in several grapevine cultivars characterised by different geographic origins.
