Seaweed extract has been applied in many crops to improve plant growth, mitigate plant stress, and enhance fruit quality. is a macroalgae that is source of phytohormones, minerals, polysaccharides and antioxidant compounds. These elements can enhance food nutritional value, contributing to human health. The objective was to analyze the potential of extract (ANE) applications in tomato, to improve physicochemical and bioactive compounds during storage. Tomato plants were cultivated divided into three treatments, foliar and soil applications of ANE (0.2%), and control. Intermediate fruits were harvested and stored for 16 days at 10 ± 1 °C and 90 ± 5% RH to evaluate some postharvest parameters. At harvest, ANE applications increased bioactive compounds, including total polyphenols content (TPC), lycopene, vitamin C and antioxidant activity (AA), as well as chemical parameters like soluble solids and pH. During storage, color parameters, β-carotene, total acidity and firmness tended to decrease as storage time increased. However, TPC, lycopene, vitamin C, AA and weight loss increased during storage. Tomatoes were positively affected by ANE applications on almost every day of storage evaluated, improving their postharvest physiology. Therefore, ANE can be used to extend tomato shelf life and is a great source of beneficial compounds, which are responsible for increasing tomato quality.

海藻提取物已应用于多种作物，以促进植物生长、减轻植物胁迫并提高果实品质。[具体海藻名称]是一种大型藻类，是植物激素、矿物质、多糖和抗氧化化合物的来源。这些元素可以提高食物的营养价值，对人类健康有益。目的是分析[具体海藻名称]提取物（ANE）在番茄上的应用潜力，以改善储存期间的理化和生物活性化合物。将番茄植株分为三种处理方式：叶面和土壤施用ANE（0.2%）以及对照。采收中期果实并在10±1°C和90±5%相对湿度下储存16天，以评估一些采后参数。采收时，ANE处理增加了生物活性化合物，包括总多酚含量（TPC）、番茄红素、维生素C和抗氧化活性（AA），以及可溶性固形物和pH等化学参数。在储存期间，随着储存时间的增加，颜色参数、β-胡萝卜素、总酸度和硬度趋于下降。然而，TPC、番茄红素、维生素C、AA和失重率在储存期间增加。在评估的几乎每个储存日，番茄都受到ANE处理的积极影响，改善了它们的采后生理状况。因此，ANE可用于延长番茄的货架期，并且是有益化合物的重要来源，这些化合物有助于提高番茄品质。
