摘要(Abstract)：

【目的】了解‘玉露香’梨果实发育中糖、酸含量变化。【方法】采用高效液相色谱法,对其糖、酸组分含量进行测定。【结果】在‘玉露香’梨果实生长发育过程中,总糖含量呈"慢—快—慢—快"的上升趋势;总酸含量呈先上升后下降的趋势;幼果期果实中的糖以山梨醇为主,酸以苹果酸为主;成熟果实中的糖以果糖为主,酸仍以苹果酸为主,成熟时果糖含量占总糖含量的43.07%,柠檬酸和苹果酸含量占总酸含量的71.9%。蔗糖含量从坐果到花后60 d内一直保持较低水平,从花后60 d开始迅速上升,直到成熟期其含量上升了3.81倍。山梨醇含量从坐果到花后75 d,含量逐渐上升并达到最大值,之后开始下降。【结论】‘玉露香’梨为高果糖型果实;按照苹果酸型、柠檬酸型和酒石酸型三大果实类型分类,属苹果酸型。
