对秋子梨、白梨、砂梨、西洋梨和新疆梨５个种内２８１个品种的果实可溶性糖及可滴定酸含量进行分析发现，秋子梨品种含糖量高，含酸量中等；西洋梨、新疆梨、白梨和砂梨的品种含糖量中等；新疆梨品种含酸量中等，余者合酸量低。秋子梨中的红八里香、平梨、面梨、山梨１６、南果４号、伏五香、早蜜、南果梨；白梨中的水罐；西洋梨中的赛斯凯尔和波１６含糖量极高，均＞１１．００％。同时探讨了糖酸比与果实风味的关系，比值＜１５．０者，果实风味多为甜酸或酸涩，品质低下；比值在１５．１—２５．０者，风味多甜酸，品质中到中上；比值为２５．１—６０．０者，风味多酸甜，品质中上到上；比值＞６０．１者，风味多为淡甜、甜或甘甜，品质中上至上。
The analysis of soluble sugar content and titratable acid content of 281 varieties in five species of Qiubao Pear, Pear, Pear, Pear, and Xinjiang pear found that the varieties of Qiubari were high in sugar and medium in acid content. Xinjiang, pear and pear and sand pear medium sugar content; Xinjiang pear varieties with moderate acid content, the other acid content is low. Autumn pear pear red Hong Li, Ping Pear, noodles pear, Yamanashi 16, South fruit No. 4, V Wu Hong, early honey, South pear fruit; white pear in the jug; High sugar content, both> 11.00%. At the same time, the relationship between sugar and acid ratio and fruit flavor was explored. The ratio of <15.0, the fruit flavor was mostly sweet or sour with low quality; the ratio was 15.1-25.0, In the ratio of 25.1-60.0, sweet and sour flavor, the quality of the upper; the ratio of> 60.1 were mostly sweet, sweet or sweet, the quality of the supremacy.
