Simulations on different grapevine cultivars with the IVINE crop growth model.

The crop growth model IVINE (Italian Vineyard Integrated Numerical model for Estimating physiological values) was developed to simulate grapevine phenological and physiological processes and it was originally optimized only for cv. Nebbiolo. The IVINE model requires a set of meteorological data as boundary conditions; moreover informations about the vineyard and the cultivar are also required as input data. The main model outputs are: the timing of phenological stages, the leaf development, the yield, the berry sugar concentration and the predawn leaf water potential. Recently IVINE model has been calibrated and validated also on different grapevine varieties (cv. Barbera, cv. Vermentino, cv Cannonau). This work shows the results of these preliminary simulations of grapevine growth processes executed using datasets assembled in the frame of MACSUR2 project.
