研究了褪黑激素处理对采后李果实生化成分和品质的影响。“圣罗莎”在1摄氏度储存40天。李子在收获后立即浸入0、1、10、100和1000 μ mol/l褪黑激素溶液中。每隔10天通过评价以下品质参数来评估李子的变化：重量损失、硬度、可溶性固形物含量（SSC）、可滴定酸（TA）、SSC：TA、抗坏血酸含量、总花青素含量、总酚含量、抗氧化活性和腐烂率。结果表明，褪黑激素在100和1000 μ mol L（-1）的治疗是有效的，在减少重量损失和保持更大的坚定性。然而，低剂量的褪黑激素处理没有积极的影响，碳水化合物，酸，生化化合物和腐败。在冷藏期间，抗坏血酸含量，总酚含量和抗氧化活性在100和1000 μ mol L（-1）褪黑激素处理的李子比对照和其他剂量。同时，1000 μ mol/l褪黑激素显著降低了衰变率，这是由于明显较高的生化化合物。这些结果表明，特别是1000 μ mol L（-1）褪黑激素处理可能是有用的技术，以延长采后李的寿命，并符合果实品质。
This study was conducted to investigate the effects of melatonin treatments on biochemical compounds and postharvest quality plum cv. "Santa Rosa" during storage at 1 degrees C for 40 days. The plums were dipped in 0, 1, 10, 100 and 1000 mu mol l(-1) melatonin solution immediately after harvest. The changes of plums were assessed at 10-day intervals by evaluating the following quality parameters: weight loss, firmness, soluble solids content (SSC), titratable acidity (TA), SSC:TA, ascorbic acid content, total anthocyanin content, total phenolic content, antioxidant activity and decay rate. The results showed that treatment of melatonin at 100 and 1000 mu mol l(-1) was effective in reducing weight loss and maintaining greater firmness. However, low doses of melatonin treatment had no effect positively on carbohydrate, acids, biochemical compounds and spoilage. During cold storage, ascorbic acid content, total phenolic content and antioxidant activity were greater in 100 and 1000 mu mol l(-1) melatonin treated plums than the control and other doses. Meanwhile, 1000 mu mol l(-1) melatonin substantially reduced decay rate, which result from significantly higher biochemical compounds. These findings suggested that especially 1000 mu mol l(-1) melatonin treatment may be useful technique to extend the postharvest life of plum with acceptable fruit quality.
