果实糖、有机酸含量及糖酸比是影响果实品质和加工的重要因素。以长白山地区10个野生居群的100株笃斯越桔果实为材料，比较了果实中糖和有机酸的含量。分析了糖酸含量与种群空间分布的相关性。同时还鉴定出了高糖低酸的种质资源，在今后的育种中具有潜在的利用价值。结果表明，长白山不同地理种群笃斯越桔的糖和有机酸含量存在差异。果糖（18.60-38.54 mg·g-1）和葡萄糖（15.77-35.08 mg·g-1）是笃斯酵母中的主要糖类，奎尼酸（16.06-20.97 mg·g-1）、柠檬酸（10.39-14.96 mg·g-1）和苹果酸（4.28-7.47 mg·g-1）是笃斯酵母中的主要有机酸。第一个种群采自东方红林场（lat.北纬42°00′，长。128°03′E）的平均糖含量和糖酸比最高。此外，还测定了位于满江林场（北纬100度）的样品7-种群1的总糖含量和糖酸比。北纬41°09′，经度。127°05′E）远高于其他99个样品，使该样品成为重要的育种种质代表。海拔和纬度是影响糖和有机酸含量的重要环境因子。果糖、葡萄糖和总糖含量与海拔高度呈正相关，与纬度呈负相关。草酸含量和糖酸比与海拔高度呈正相关，有机酸含量与纬度无显著相关性。
Sugar and organic acid contents as well as sugar-to-acid ratio of fruit are important factors affecting fruit quality and processing. In this study, we compared sugar and organic acid contents of Vaccinium uliginosum (bog bilberry) fruit harvested from 100 plants across 10 wild populations growing in the Changbai Mountains of China. Correlation of sugar and acid contents with the spatial distribution of these populations was accessed. Germplasm with high sugar and low acid with potential for use in future breeding was also identified. Results showed that sugar and organic acid contents varied among different V. uliginosum populations in the Changbai Mountains. Fructose (18.60–38.54 mg·g−1) and glucose (15.77–35.08 mg·g−1) were the main sugars, whereas quinic (16.06–20.97 mg·g−1), citric (10.39–14.96 mg·g−1), and malic (4.28–7.47 mg·g−1) acids were the main organic acids in V. uliginosum. The first population collected in the Dongfanghong forest farm (lat. 42°00′N, long. 128°03′E) showed the highest average sugar content and sugar-to-acid ratio among the sampled populations. Moreover, total sugar content and sugar-to-acid ratio of Sample 7—Population 1, which is located at Manjiang forest farm (lat. 41°09′N, long. 127°05′E) was much higher than the other 99 samples, making this sample representative of important germplasm for breeding. Altitude and latitude were important environmental factors affecting sugar and organic acid contents. Fructose, glucose, and total sugar contents were positively correlated with altitude and negatively correlated with latitude. Oxalic acid content and sugar-to-acid ratio were positively correlated with altitude, and there was no significant correlation between organic acid contents and latitude.
