The evolution of chlorophylls a and b, and total carotenoids levels we
re estudied during ripening of grape berries of different cultivars of
vinification grape (white and red grapes). The content of these pigme
nts decrease continuosly during ripening. We have found considerable l
evels of photosyntetic pigments in skin of grape in industrial maturat
ion. Climatic conditions have a great influence in the levels and the
evolution of these pigments.
