酿酒葡萄成熟特性的研究

Study on the Berry Mature Property of Wine Varieties of Grape

葡萄浆果成熟过程中,存在着多方面的变化。只有含糖量、含酸量的变化最有规律,最能代表葡萄品种的成熟特性。含糖量的变化与logistic曲线、含酸量的变化与对数曲线拟合性最好。不同品种成熟特性的差异,主要表现为含糖量上升速率与含酸量下降速率的不同。气象因素能明显影响葡萄的成熟特性,最终造成同一品种在不同地区成熟度的差异。

Results showed that the juice components of the berries changed continually during its ripening. The sugar content was changed with a 'S' curve, while the acids showed a logistical curve. They were probably the best index for determining the berry maturity. The variation of berry maturity among varieties was probably attributed to the variation of the increasing rate of sugar accumulation and the decreasing rate of the acids. Ripening process of grape berries was significantly influenced by the climate.
