摘要
对秋红晚蜜桃结果枝不同部位的果实,测定其总糖和可滴定酸的含量,计算糖酸比。结果表明:西南方向上部的果实含糖量最高,东南方向下部的果实含糖量最低。西北方向的中部果实含酸量最高,东南方向上部果实含酸量最低。西南方向上部的果实糖酸比值最高,西北方向下部果实糖酸比值最低。
The sugar- acid ratio of Qiurni ,which were plucked from the different fruit branching part on October 16th 2006, were calculated by determining the content of total carbohydrate and titratable acidity in the fruits . The results showed that, the fruits growing on the upper parts of south-western branches had proportion the highest content of sugar while those on the lower parts of the south-eastern branches the lowest. Those on the middle part facing the north-west had proportion the highest content of acid and those on the upper part facing the south-east the lowest. The sugar-acid ratio of the fruits on the top part facing the west-south was the highest content and those on the lower part facing the north-west proportion the lowest content. The above could serve the function of improving the qualities of the fruits and guiding the farmers in fruit tree growing.
