Since 2010, we have developed a scientific project that uses as model the asynchronous cluster of Pinot Noir cultivar. As many fruits growing in a cluster, grapes suffer from developmental variability that is at the greatest at the onset of ripening also named véraison (french viticulturist name that means “change of color of grape berries”). The goal of the project is to identify the molecular factors that are responsible for the reduction of developmental variability towards maturity.

In grapevine, quality of grape composition at harvest relies on the subtle ratio between vegetative and reproductive growth, also named vine balance. In cool climate regions, the excess of water and nitrogen in the soils tends to maintain high vine vigor in vineyards, which favor vegetative vigor. We developed a research project aimed at understanding the relationships between vegetative and reproductive growth under reduced vine vigor conditions. Our project focuses on the quantification of several classes of hormones that are involved in the growth of expanding shoots and developing berries during the growing season.
