This study describes the approach of H NMR metabolomic profiling for the differentiation of zucchini produced under different conditions of water irrigation (desalinated seawater -0.397 dS/m, 0.52 €/m vs groundwater -2.36 dS/m, 0.29 €/m) and ventilation (surface area of the vent openings/greenhouse area was 15.0% for one sector and 9.8% for the other). Overall, 72 extracts of zucchini ( Cucubirta pepo L. cv Victoria) under four different conditions were regularly analyzed during the spring-summer cycle from April to July 2017. We have found that zucchini plants irrigated with desalinated seawater increased the zucchini production yield, presented fruits with higher concentration of glucose, fructose, and vitamin B3, and displayed an increased antioxidant activity. On the contrary, plant groundwater irrigation produced the increment of sucrose level that could rise the sweetness perception of the fruits. Finally, the ventilation variable produced a higher concentration of trigonelline, histidine, and phenylalanine but only on those zucchinis irrigated with groundwater.
本研究描述了利用 1 H NMR 代谢组学分析方法区分在不同灌溉条件（海水淡化水 -0.397 dS/m，0.52 欧元/立方米与地下水 -2.36 dS/m，0.29 欧元/立方米）和通风条件（通风口面积/温室面积分别为 15.0%和 9.8%）下生长的西葫芦。总体而言，2017 年 4 月至 7 月，在春季-夏季周期内，定期分析了 72 种不同条件下的（ Cucubirta pepo L. cv Victoria）西葫芦提取物。我们发现，用海水淡化水灌溉的西葫芦植物增加了西葫芦的产量，果实中葡萄糖、果糖和维生素 B3 的浓度更高，抗氧化活性也增强。相反，地下水灌溉增加了蔗糖水平，从而提高了果实的甜度。最后，通风变量导致瓜氨酸、组氨酸和苯丙氨酸的浓度升高，但仅在那些用地下水灌溉的西葫芦中。
