| 摘 要： | 【目的】以河北怀来霞多丽葡萄为研究对象,分析温度、日照时间对霞多丽葡萄成熟度指标的影响。【方法】根据2004—2008这5年的田间试验结果与气象材料,综合运用相关性分析、主成分分析、回归分析以及方差分析等方法进行分析。【结果】4月最高温度、5月平均温度、5月最低温度、7月最高温度、7月日照时间对霞多丽葡萄糖度的积累有显著影响。5月活动积温、6月最高温度对霞多丽葡萄总酸含量有显著影响。5月活动积温、8月日照时间、8月最高温度、9月最高温度对霞多丽葡萄糖酸比值有显著影响。4月活动积温、7月日照时间对霞多丽葡萄的pH具有显著影响（在0.05水平上）。【结论】不同时段的温度和日照时间对怀来地区霞多丽葡萄的糖度、酸度、糖酸比、pH等成熟度指标产生不同程度的规律性影响。

| Abstract: | 【Objective】 Taking the Chardonnay grapes in Huailai county, Hebei province as the object of this study, the effects of temperature, duration of sunshine on the grape maturity indices were analyzed. 【Method】 Based on five-year field test results in 2004-2008 and meteorological conditions, a comprehensive analysis was made using the correlation analysis, principal component analysis, regression analysis and variance analysis methods.【Result】The results showed that the highest temperature in April, mean temperature of May, the lowest temperature in May, the highest temperature in July and duration of sunshine in July were the most important factors affecting total sugar content of Chardonnay grape. Active accumulated temperature in May, the highest temperature in June had a significant effect on the total acid content. Active accumulated temperature in May, duration of sunshine of August, the highest temperature in August and September had a significant effect on sugar/acid ratio. Active accumulated temperature in April, duration of sunshine in July were the most important factors affecting pH value (0.05 level). 【Conclusion】In Huailai region, temperature and duration of sunshine have different effects on the Chardonnay grapes’ sugar content, acidity content, sugar acid ratio and pH value at different stages of growing season. |
