摘要

本研究旨在评估水杨酸（SA）对石榴（Punica granatum L.）品质和贮藏寿命的影响，并在水杨酸溶液中进行了叶面施用和果实采后浸渍两个实验。在第一个实验中，石榴树以0、1、3或9mM L-1的浓度喷洒。在5°C下储存两个月后，对石榴果实的离子泄漏、总可溶性固形物和腐烂进行了检测。结果表明，与对照相比，处理后的果实离子渗漏和真菌腐烂减少，可溶性固形物总量增加。在第二个实验中，将水果浸泡在浓度为0、1或3 mM L-1的SA中，并在5°C下储存两个月，以研究水杨酸对储存样品的冷害（Cl）、腐烂和化学特性的影响。结果表明，SA的采后施用显著提高了果实的总抗氧化能力，减少了果实的冷害和腐烂。然而，与对照相比，它对果实的总酚、总可溶性固形物、总花青素和颜色没有显著影响。

Effect of pre- and postharvest application of salicylic acid on quality attributes and decay of pomegranate fruit (cv. Shishe-Kab)

This study was aimed to assess the effect of salicylic acid (SA) on quality and storage life of pomegranate (Punica granatum L.) and performed in two experiments including foliar application and postharvest dipping of fruits in salicylic acid solutions. In the first experiment, pomegranate trees were sprayed at concentrations of 0, 1, 3 or 9 mM L-1. After two months of storage at 5 °C, ionic leakage, total soluble solids, and decay of pomegranate fruit was examined. The results showed that ionic leakage and fungal decay decreased and total soluble solids increased in treated fruits compared to the control. In the second experiment, fruits were dipped in SA at concentrations of 0, 1 or 3 mM L-1 and stored at 5 °C for two months to investigate the effects of salicylic acid on chilling injury (Cl), decay, and chemical attributes of stored samples. The results revealed that postharvest application of SA significantly increased total antioxidants and decreased chilling injury and decay of treated fruits. However, it did not significantly affect total phenol, total soluble solids, total anthocyanin and colour of fruits compared to the control.
