Rutin is a widely distributed natural flavonoid in higher plants and is considered a signal molecule responsible for inducing defense responses against biotic and abiotic stresses. This study evaluated the effect of foliar spray of rutin (0, 0.5, 1.0, 1.5, and 2.0 mmol L⁻¹) 20 days after transplanting the seedlings to the pots, in three consecutive applications. The effect of rutin on the metabolism of tomato plants was evaluated through on photosynthetic performance, crop development and yield, fruit bioactive compounds, and antioxidant activity in tomato variety ‘IPA 6’. Beneficial effects of rutin in tomato are associated with increased photosynthetic performance and higher concentration of leaf primary metabolites, such as chlorophyll, carbohydrates, and protein; which provides evidence for improved plant growth parameters and fruit production. At the same time, rutin pulverization also resulted in a higher concentration of secondary compounds in tomato fruits such as polyphenol, flavonoid, lycopene, β-carotene, and lutein, providing them a greater antioxidant capacity. Cross-talks among plant physiological responses, fruit production and fruit quality as a result of rutin application implicates the benefits of using this elicitor for sustainable commercial cultivation of Solanum lycopersicum.

芦丁是高等植物中广泛分布的天然黄酮类化合物，被认为是负责诱导针对生物和非生物胁迫的防御反应的信号分子。本研究评估了叶面喷洒芦丁（0、0.5、1.0、1.5 和 2.0 mmol L ^-1) 将幼苗移植到盆中后 20 天，连续施用 3 次。通过对番茄品种“IPA 6”的光合性能、作物发育和产量、果实生物活性化合物和抗氧化活性的影响，评估了芦丁对番茄植物代谢的影响。芦丁在番茄中的有益作用与光合性能的提高和叶片初级代谢物浓度的提高有关，如叶绿素、碳水化合物和蛋白质；这为改善植物生长参数和果实产量提供了证据。同时，芦丁粉碎还导致番茄果实中多酚、黄酮类、番茄红素、β等次级化合物的浓度较高。-胡萝卜素和叶黄素，为它们提供更强的抗氧化能力。由于芦丁应用，植物生理反应、果实产量和果实质量之间的相互影响暗示了使用这种诱导剂对茄属植物进行可持续商业种植的好处。
