摘要
以优质南果梨为试材，着重研究了南果梨采摘后在常温条件下2-26天内的可溶性固形物、可溶性糖、可滴定酸以及糖酸比变化过程，发现在这段时间内南果梨的上述指标在后熟期内（果实采摘后2-18天内）升高，在腐败期（果实采摘后18-26天内）下降，南果梨糖酸比为27左右，属品质极佳的梨品种。通过测定发现，南果梨氨基酸含量较高，尤其是人体必需氨基酸含量丰富。
The top quality nanguo pear from datun of haicheng city was used as materials. During 2-26 days, the contents of soluble solids, soluble sugar and sugar-acid ratio in nanguo pear rised in the ripening process （2-18 days after plucking） and lowered in the corrupting process （18-26 days after plucking）, the sugar-acid ratio of nanguo pear is about 27, so its quality is very good; nanguo pear＇s total content of amino acids, special the content of essential amino acids are very high.
