The effect of controlled deficit irrigation (CDI) on the accumulation of carotenoids, polyphenols and l-ascorbic acid was studied in conventional and high lycopene tomato cultivars. Plants were initially irrigated to cover 100%ET and after the fruit set phase, the dose was reduced to 75% or 50% of ET. CDI had no significant effect on the accumulation of carotenoids, while it increased the levels of the hydroxycinnamic acids chlorogenic and ferulic acids, the flavonoid rutin and l-ascorbic acid. Nevertheless, there were important interactions and this effect was highly dependent on the year and site of cultivation. Certain growing areas would be more favorable to supply high quality markets, and, fortunately, CDI would maximize polyphenol (100-75%ET) and l-ascorbic acid (100-50%ET) in these areas. A combination of the best genotype and growing area with CDI would offer high quality products, preserving a scarce resource: water.
研究了常规和高番茄红素番茄品种中控制性亏缺灌溉（CDI）对类胡萝卜素、多酚和 l-抗坏血酸积累的影响。在果实形成阶段之前，植物最初以覆盖 100%ET 的水量进行灌溉，然后将水量减少到 ET 的 75%或 50%。CDI 对类胡萝卜素的积累没有显著影响，但它增加了羟基肉桂酸绿原酸和阿魏酸、类黄酮芦丁和 l-抗坏血酸的水平。然而，存在重要的相互作用，这种影响高度依赖于种植的年份和地点。某些种植区将更有利于供应高质量市场，幸运的是，CDI 将最大限度地提高这些地区的多酚（100-75%ET）和 l-抗坏血酸（100-50%ET）。将最佳基因型与 CDI 与生长区相结合，将提供高质量的产品，同时节约稀缺资源：水。
