Potential quality of grapes: basis of a practical estimation model

Abstract

The agrometeorological model of potential grape berry sugar content joined to the carbon balance model of the triptych « Exposed Leaf Area – Dry Matter Production or Yield – Vigour », with the consideration of moderate water limitation standards and the general experience of berry maturity, lead to the proposal of a practical model for evaluating the potential grape berry quality useful for training vineyards.
