- 摘要:
- 以新疆喀什地区3个鲜食枣（Zizyphus jujuba Mill.）品种果实为试材，采用高效液相色谱法（HPLC）对“冬枣”“伏脆蜜”“京沧1号”3个鲜食枣品种果实发育过程中糖类和有机酸类各组分含量进行测定,比较不同品种间的果实生长发育过程中糖酸积累差异，以期为揭示其动态变化规律提供参考依据。结果表明：3个鲜食枣品种果实中糖以蔗糖为主，且属蔗糖积累型果实，糖组分含量随果实发育呈整体上升趋势；有机酸以苹果酸为主，且属苹果酸型，酸组分含量随果实发育呈先增加后下降趋势；糖类和有机酸类各组分间各自存在一定相关性；蔗糖和苹果酸是3个鲜食枣品种果实全红期糖酸组分首要指标。
- Abstract:
- Taking the fruits of three fresh jujube (Zizyphus jujuba Mill.) varieties in Kashgar，Xinjiang as test materials，the contents of sugar and organic acid components in the fruit development of ‘Dong jujube’ ‘Fucuimi’ and ‘Jingcang 1’ were determined by high performance liquid chromatography (HPLC) method,in order to provide reference for comparing the difference of sugar and acid accumulation in fruit growth and development among different varieties and reveal their dynamic changes.The results showed that the sugar of the three fresh jujube varieties was sucrose，and the sugar component content increases with the fruit development；the organic acid content was the correlation of sugar and organic acid；and sucrose and malic acid were the primary indexes of sugar acid components of the three fresh jujube varieties.
