| Sensory evaluation of grapes (Vitis vinifera L.) plays a key role in determining the harvest time in grapevine varieties. The harvest time of cv. Carménère is one of the latest of Chile. During the season 2007-2008, the evolution of the appearance of Carménère seeds was evaluated as a harvest criterion, comparing it with the chemical and phenolic ripening. The samples were obtained from an organic vineyard located in Curicó Valley, Chile. Starting at 16 ºBrix, 100 seed berries samples were collected weekly from medium vigor vines in order to register photographically the ventral and dorsal sides of each seed. In addition to the seed tannins percentage, the extractable anthocyanins, total anthocyanins and total polyphenols index, as well as the titratable... |

| Fruit size is a very important quality attribute in cherry trees. Appropriate canopy and crop load management are, therefore, required to obtain an adequate balance between the yield and fruit size. A study was carried out during the 2007-2008 season in the Maule Region of Chile to evaluate the effect of increasing levels of dormant pruning (Control, no removal; Soft pruning, 15% removal; Moderate pruning, 30% removal and Intense pruning, removal of 50% of the fruiting wood) on the fruit yield, quality (size, fruit weight, soluble solids and fruit firmness) and crop value of sweet cherries (Prunus avium L.) cv. 'Bing' on the dwarfing rootstock, 'Gisela 6'. Treatments at the 30 and 50% removal intensities had a strong effect on yield reduction (36.1% and... |
