Abstract

Abstract The influence of varieties and the effect of mulching film on antioxidant capacity, polyphenol content, ascorbic acid content, and yield of tomato fruits were investigated. Results of two years (2012 and 2013) investigations were compared. The results proved a statistically significant effect of year, mulching film, and variety on the content of total polyphenols (0.92–1.49 g gallic acid equivalents per kg of fresh weight (FW), ascorbic acid (26.66–38.62 mg per 100 g FW), and antioxidant capacity (1.12–1.94 g ascorbic acid equivalents per kg FW), while the values were the highest in 2013 and in uncovered soil. Conversely, a higher yield was found in mulching film compared with uncovered soil, also in 2013 (48.65–120.38 t ha−1). There was a negative correlation between the yield and the content of bioactive compounds (BC) and antioxidant capacity. The content of bioactive substances, antioxidant capacity, and yield of tomato fruits is dependent on the vintage, agronomical interventions, and genotype.

地膜对番茄品种生物活性成分的影响

摘要研究了不同品种和地膜覆盖对番茄抗氧化能力、多酚含量、抗坏血酸含量和产量的影响。比较了两年（2012年和2013年）的调查结果。结果证明，年份、地膜和品种对总多酚含量（0.92–1.49 g没食子酸当量/kg鲜重（FW）、抗坏血酸（26.66–38.62 mg/100 g FW）和抗氧化能力（1.12–1.94 g抗坏血酸当量/kg FW）的影响具有统计学意义，而这一值在2013年和未覆盖土壤中最高。相反，与未覆盖的土壤相比，地膜的产量更高，同样在2013年（48.65–120.38 t ha−1）。产量与生物活性化合物（BC）含量和抗氧化能力呈负相关。番茄果实的生物活性物质含量、抗氧化能力和产量取决于年份、农艺干预和基因型。
