Clone performance under different environmental conditions in California

The use of the term bioprotection in winemaking refers to the use of non-chemical methods to prevent the development of undesirable microorganisms (yeasts and/or bacteria). The reason for studying this method is mainly as a natural alternative to the addition of sulfites during the pre-fermentation stages. In winemaking, the addition of s02 has multiple functions, the main ones being antiseptic and antioxidant power.

A work involving the finding, the description and the recovery of old grapevine varieties from the north and north east of Spain was begun in the CSIC in the year 1987.

Phenolic compounds are very importants in crop plants, which is why there have been the subject of a large number of studies

Dans la Région de la Bairrada (Litoral-Centre du Portugal), on a étudié au 1999, l’influence des différents systèmes de conduite sur le cépage rouge “Baga”, le plus important de la Région.

Anticipation in the possible responses of grapevines to environmental variations is key to adjust field work in view of a more effective management. This idea has been the driving force behind the current work, which seeks to understand the interaction patterns of the vine with its habitat throughout the growing cycle.
