High temperature effect on Cabernet Sauvignon berries

The experiment was conducted using four 11-year-old potted grapevines of V. vinifera L. cv. Cabernet Sauvignon grafted on SO4 (Selection Oppenheim No. 4) grown in a phytotron. Vines were trained on a Guyot trellising system and each vine carried 4-10 clusters of grapes. The experiment started approximately 1 week before veraison, when berry softening started, and continued to fruit maturity. The two temperature regimes consisted of a high day (06.00–20.00 h) temperature (max.35C) and a control (max. 25C). Under both conditions, the night-time (20.00–06.00 h) temperature was 20C.
