吐鲁番葡萄果粒增重及糖酸含量变化规律

Analysis of Change Regular of Increasing Weight and Content of Sugar Acid for Grape in Tulufan

根据实测资料统计分析表明 ,吐鲁番盆地 4种主栽品种葡萄果粒重、浆果含糖量、成熟系数 (糖酸比 )与开花后≥ 1 5℃积温呈极显著的logistic生长曲线 ,而含酸量与开花后≥ 1 5℃积温呈极显著的指数关系 ,并据此确定了上述各生长因子或品质因子变化的关键时期。

According to the actual data showed that grape′s weight,content of sugar mature coefficient (the rate of sugar and acid)have assumed extreme remarkable Logistic growing bend line with ≥15℃ accumulated tempreture of after blossom for four kinds of main plant breeds in Tulufan Basin,but extreme remarkable exponential function for content of acid with ≥15℃ accumulated tempreture of after blossom,so that the crucial period of different growing element or quality element were defined which provides scientific basis for scientific management measure or develop different uses of grape picking period.
