Abstract:
Four varieties，namely ‘Cabernet sauvignon’，‘Merlot’，‘Chardonnay’ and ‘Italian riesling’were selected as materials.The vines were subjected to different fruit zone treatments to study the effect of fruit zone management on the contents of the sugars，acids，total phenols，tannins and total anthocyanins.The results showed that：the grape clusters were located in the zone between the height of 40 cm to 120 cm above the ground from each variety.However，quality wines were difficult to obtain from these grapes，which located in different height above the ground，as the heterogeneity of grape maturity.Higher cluster produced higher quality grapes in all of four varieties.The contents of sugars，total anthocyanins，total phenols and tannins were significant higher in two red grapes from higher fruit zones.The acid from each variety was too low for winemaking，which should be paid enough attention.The training systems which have a uniform fruit zones were suggested to obtain quality wines，and a higher fruit zone treatment was suggested for this area.
