LOPES, J. et al. Thermal requirementes, duration and precocity of phenological stages of grapevine cultivars of the portuguese collection. Ciência Téc. Vitiv. [online]. 2008, vol.23, n.1, pp.61-71. ISSN 0254-0223.

Temperature is the major climate element for grapevine development, controlling the rhythm at which several phenological stages like budbreak, flowering, veraison and maturity occur during the biological cycle. In Portugal, information about the thermal requirements of the different cultivars for wine production is lacking. This work aims to evaluate the thermal durations of each development phase of grapevine cultivars of the portuguese collection, located at Estação Vitivinícola Nacional, Dois Portos. Cultivars were classified as short-cycle, medium-cycle or long-cycle according to the duration of both each phase of development and the full cycle. They were also classified as early-season, mid-season or late-season cultivars, starting on the 1st of January.
