- 摘要:
- 以“大黄姑娘”酸浆为试材，采用随机区组设计，盆栽的方式，研究了施用不同浓度NaCl对酸浆植株生长及果实品质的影响，旨在探明酸浆的耐盐性及果实品质优化的条件，为设施栽培生产高品质酸浆提供参考依据。结果表明：低浓度NaCl处理对酸浆植株生长影响不大，当浓度达到0.25 mol?L-1时，其生长指标参数值和酶活性均显著低于对照。果实单果质量、出汁率随盐浓度的增加而减小；果实硬度、维生素C含量、可溶性糖含量、有机酸含量均随NaCl浓度的增加先增大后减小，且在0.20 mol?L-1 NaCl浓度时达到最优，极显著高于对照。果实糖酸比虽无一定变化规律，但也在0.20 mol?L-1 NaCl浓度时极显著高于对照。综合来看，NaCl处理会对酸浆植株生长产生抑制，但又会在一定程度上提高果实品质。该试验条件下，酸浆植株生长可承受的最大NaCl浓度为0.20 mol?L-1，且在该浓度处理下果实品质最优。
- Abstract:
- Taking ‘Dahuang Guniang’ alkekengi as test material，a random block design and a pot planting method were used to study the effects of applying different concentrations of NaCl on the growth of physalis plants and fruit quality.The results showed that low concentration NaCl treatment had little effect on the growth of physalis plants.When the concentration reached 0.25 mol?L-1，its growth index parameter value and enzyme activity were significantly lower than those of the control.The single fruit quality and juice yield decreased with the increase of salt concentration；the fruit hardness，vitamin C content，soluble sugar content，organic acid content all increased first and then decreased with the increase of NaCl concentration，and when NaCl concentration was 0.20 mol?L-1 ,those indexes were the best,which was significantly higher than the control.Although the sugar-acid ratio of the fruit had no regular change，it was also significantly higher than the control at 0.20 mol?L-1NaCl concentration.Taken together，NaCl treatment will inhibit the growth of physalis plants，but will improve the quality of the fruit to a certain extent.Under this test condition，the maximum NaCl concentration that physalis plants could bear was 0.20 mol?L-1，and the fruit quality was optimal under this concentration.
