-- Exposure to low temperatures is one of the main factors causing the coulure in grapevine, due to its effect on the plant’s photosynthesis and carbon metabolism. To test the effect of a chilling night on carbon reserves of inflorescences of Pinot Noir, fruiting cuttings that have undergone a low-temperature night at 4°, 0° and -3 ° C were used to determine the levels of carbohydrates (glucose, fructose, sucrose and starch) in the inflorescences. Microscopic observations of inflorescences after a -3 ° C night were performed. The levels of glucose and fructose fluctuated during the first hours after a 4 and 0 ° C night, but it is especially after a chilling night at -3 ° C that a strong mobilization and consumption of carbohydrates in the inflorescence were observed. -- Key words: Cold stress, carbohydrates, inflorescence, grapevine, coulure.
