摘要/Abstract

摘要： 以杏李恐龙蛋（Prunus domestica × armeniaca konglongdan）为试验材料,研究了不同浓度水杨酸处理对其采后生理和贮藏品质的影响。结果表明,与对照相比,不同浓度水杨酸处理均能抑制恐龙蛋果实的乙烯释放速率,降低果实的呼吸强度,保持果实较高的硬度,降低果实失重率和腐烂率,此外,水杨酸处理可维持果实较高的可溶性固形物含量,同时显著提高果实的抗氧化酶活性。水杨酸处理能增强采后恐龙蛋果实的耐贮性和维持较高的贮藏品质,尤其以0.1 mmol/L水杨酸处理的保鲜效果最佳,可作为提高恐龙蛋果实采后耐贮性、延长其保鲜期的适宜处理条件。

Abstract: The effects of different concentrations of salicylic acid on postharvest physiology and storage quality of Prunus domestica × armeniaca konglongdan were studied. The results showed that compared with the control, different concentrations of salicylic acid treatment could inhibit the ethylene release rate of konglongdan, reduce the respiratory strength of the fruit, maintain a high hardness of the fruit, and reduce the weight loss rate and decay rate of the fruit. In addition, the salicylic acid treatment could maintain a high content of soluble solids, and significantly improve the antioxidant enzyme activity of the fruit. Salicylic acid treatment could enhance the storage tolerance of postharvest konglongdan and maintain high storage quality, especially the low concentration salicylic acid （0.1 mmol/L） treatment having the best preservation effect, which could be used as a suitable treatment condition to improve the postharvest storage tolerance of konglongdan and prolong its freshness.

Key words: Prunus domestica × armeniaca konglongdan, postharvest preservation, salicylic acid, storage quality
