The results showed that soil electrical conductivity, (EC2: 7 dS/m) increased soluble solids, lycopene content, total phenolic content, hydrophilic and lipophilic radical scavenging activities (HRSA and LRSA) by 14.2, 149, 20, 46.4, and 19.0%, respectively, compared with control. Under 0.5% spent engine oil (SEO), flavonoid content decreased by 21.7% compared with the control. HRSA and LRSA of fruits subjected to EC2/SEO1 treatment were, respectively, 45.9 and 35.5% lower than control. The a/b ratio was positively and significantly ( < 0.01) correlated with β-carotene (R = 0.78), lycopene (R = 0.68), total vitamin C (R = 0.71), α-tocopherol (R = 0.83), γ-tocopherol (R = 0.66), HRSA (R = 0.93), LRSA (R = 0.80), and soluble solids (R = 0.84) suggesting that it may be a promising indicator of fruit quality in areas affected by such constraints. The research revealed that combined stresses induce responses markedly different from those of individual treatments, which strain the need to focus on how the interaction between stresses may affect the functional quality of tomato fruits.
结果表明，与对照相比，土壤电导率（EC2: 7 dS/m）使可溶性固形物、番茄红素含量、总酚含量、亲水性和亲脂性自由基清除活性（HRSA和LRSA）分别提高了14.2%、149%、20%、46.4%和19.0%。在0.5%废机油（SEO）处理下，类黄酮含量比对照降低了21.7%。经EC2/SEO1处理的果实的HRSA和LRSA分别比对照低45.9%和35.5%。a/b比值与β-胡萝卜素（R = 0.78）、番茄红素（R = 0.68）、总维生素C（R = 0.71）、α-生育酚（R = 0.83）、γ-生育酚（R = 0.66）、HRSA（R = 0.93）、LRSA（R = 0.80）和可溶性固形物（R = 0.84）呈显著正相关（<0.01），这表明在受此类限制影响的地区，它可能是果实品质的一个有前景的指标。该研究表明，复合胁迫诱导的反应与单独处理的反应明显不同，这凸显了需要关注胁迫之间的相互作用如何影响番茄果实的功能品质。
