摘要:
本文以涵盖我国6个生态品种群的118份桃地方品种为试验材料,对其糖酸组分进行全面分析,以明确不同桃区果实糖酸组分分布特性,为优异糖酸种质筛选提供依据。应用斐林试剂测定果实可溶性糖含量;应用NaOH测定果实可滴定酸含量;应用高效液相色谱(HPLC)技术对果实糖组分、酸组分进行测定。结果表明:1)可溶性糖、山梨醇、蔗糖、总糖在云贵高原桃区、华南亚热带桃区品种中均表现出高数值分布特征,而在西北高旱桃区中则表现出低数值分布特征;果糖在长江流域、东北高寒桃区品种中表现出高数值分布特征。可滴定酸、柠檬酸、奎宁酸、苹果酸、总酸在华北平原桃区、长江流域桃区、华南亚热带桃区品种中均表现出低数值分布特征,而在西北高旱桃区则表现出高数值分布特征。糖酸比、固酸比、总糖/总酸在华北平原桃区、长江流域桃区、华南亚热带桃区品种中均表现出高数值分布特征,而在西北高旱桃区、云贵高原桃区、东北高寒桃区则表现出低数值分布特征。2)六个生态品种群的品种,果糖所占比例以长江流域桃区最高,葡萄糖以西北高旱桃区最高,山梨醇以华南亚热带桃区最高,而东北高寒桃区最低,蔗糖所占比例在不同生态区无明显差别。柠檬酸所占比例以长江流域桃区最高,而华南亚热带桃区最低,奎宁酸所占比例以华南亚热带桃区最高,琥珀酸、苹果酸所占比例在不同生态品种群间无明显差异。

Abstract:
Abstract: Studies were conducted on the distributions of sugar and acids contents of 118 doses of peach accessions, which contain six cultivar groups in China, for providing reliable evidences of high quality peach breeding selection. In this study Soluble sugar was detected by fehling reagent. Titratable acidity was detected by NaOH.Sugar and organic acid compositions in 295 peach accessions were detected using the high performance liquid chromatography (HPLC) method. Result:1) Cultivars derived from Yunnan-Guizhou plateau, Southern China Contain high value of sugar compositions (fructose, sucrose), soluble sugar, total sugar, but those are low in cultivars of Northwest China. Cultivars of Changjiang River Region and Northeast China contain high value of fructose.Cultivars derived from North China Plain, Changjiang River Region and Southern China contain low value of titratable acidity , some acid compositions(citrale, quinate, malate) and total acid, but those are high in cultivars of Northwest China. Cultivars derived from North China Plain, Changjiang River Region and Southern China contain high value of SS/TA, SSC/TA and ‘Total sugar/ Total acid’, but those are low in cultivars of Northwest China, Yunnan-Guizhou plateau and Northeast China. 2) For sugar compositions in different cultivars, Ratio of ‘fructose to total sugar’ is the highest in Changjiang River Region cultivars, Northwest China cultivars have a high level of ‘glucose to total sugar’. The ratio of ‘sorbitol to total sugar’ is the highest in Southern China cultivars, but the Northest China cultivars have the lowest level. Ratio of ‘sucrose to total sugar’ have no significant difference in six ecological cultivar groups. For the analysis of acid compositions, Changjiang River Region cultivars have high level of citrale, but cultivars of Southern China have a lower level, which have the highest level of quinate. The ratios of succinic and malate acids have no significant difference in six ecological cultivar groups.
Key words:  Local cultivar  Sugar compositions  Acid compositions
