摘要
以五年生灰枣为试材,研究了不同浓度复合盐碱溶液胁迫对灰枣果实内在品质的影响,为盐渍化土地灰枣种植提供参考。结果表明,0.2%,0.4%和0.6%的复合盐碱胁迫降低了灰枣果实中的有机酸含量,提高了糖酸比。0.2%和0.4%的复合盐碱胁迫提高了灰枣果实的Vc含量,0.6%的复合盐碱胁迫则降低了灰枣果实的Vc含量。0.4%的复合盐碱胁迫显著提高了灰枣果实的可溶性糖含量,0.2%和0.6%的复合盐碱胁迫对可溶性糖含量影响不大。0.2%和0.4%的复合盐碱胁迫降低了灰枣果实可溶性蛋白含量,0.6%的复合盐碱胁迫则提高了灰枣果实可溶性蛋白含量。综合分析表明,0.4%的复合盐碱胁迫处理的灰枣果实品质较好。
To provide cultivation reference for Zizyphus jujuba‘Huizao’ in salinized land ,five-year-old Huizao plants were used as the experimental materials to study the stress effects of mixed salt-alkali with different concentrations on the internal quality of Huizao fruit .The results showed that the sugar-acid ratio was improved and organic acid content was decreased under mixed salt-alkali stresses （concentrations were 0 .2% ,0 .4% and 0 .6% ） . The fruit vitamin C content was increased under the stresses of 0 .2% and 0 .4% mixed salt-alkali , but it was reduced under the one of 0 .6% mixed salt-alkali .The content of soluble sugar was significantly increased under 0 .4% mixed salt-alkali ,but lit-tle influence by 0 .2% and 0 .6% mixed salt-alkali was found .The content of soluble protein was decreased under stress-es of 0 .2% and 0 .4% mixed salt-alkali ,while it became improved under 0 .6% mixed salt-alkali stress .Comprehensive analysis indicated that the fruit internal quality of Huizao was superior under the stress of 0 .4% of mixed salt-alkali .
