The accumulation of polyphenols and l-ascorbic acid was evaluated under conventional (integrated pest management, IPM) and organic farming, as means to increase the accumulation of chemoprotective compounds. The effect of genotype was considerably higher than the growing system, in fact it is determining. 'Kalvert', a high-lycopene cultivar, outstood for the accumulation of most polyphenols, though low-carotenoid cultivars with high accumulation were also detected. Organic farming significantly increased the levels of caffeic acid by 20%, but reduced those of ferulic acid and naringenin by 13% and 15% respectively. A strong interaction with the environment was detected: in Navarra the differences were limited, while in Extremadura lower contents of ferulic acid and higher contents of chlorogenic acid and rutin were found in organic farming for certain cultivars. The effect of organic farming on l-ascorbic acid was dependent on cultivar and environment and it only led to an increase in Extremadura by 58%.
评估了常规（病虫害综合防治，IPM）和有机种植条件下多酚和L-抗坏血酸的积累情况，以此作为增加化学保护化合物积累的手段。基因型的影响远高于种植系统，实际上它起决定性作用。“卡尔弗特”是一种高番茄红素品种，在大多数多酚的积累方面表现突出，不过也检测到了一些高积累的低类胡萝卜素品种。有机种植显著使咖啡酸水平提高了20%，但阿魏酸和柚皮素水平分别降低了13%和15%。检测到与环境有强烈的相互作用：在纳瓦拉，差异有限，而在埃斯特雷马杜拉，某些品种在有机种植条件下阿魏酸含量较低，绿原酸和芦丁含量较高。有机种植对L-抗坏血酸的影响取决于品种和环境，仅在埃斯特雷马杜拉使其增加了58%。
