Consumption of broccoli is increasing steadily worldwide because of the interest in its bioactive composition and nutritive value for health promotion. Novel broccoli cultivars to be established under current adverse conditions in production areas (aggressive environmental conditions and saline irrigation waters) need to maintain physical and nutritional quality for consumption and year-round supply to the markets. The newly introduced cultivars 'Naxos' and 'Parthenon' have been selected as potential candidates to replace the currently underperforming 'Nubia' variety. We aimed to compare the physical and phytochemical quality (glucosinolates, hydroxycinnamic acids, flavonoids, vitamin C and minerals), as well as the in vitro antioxidant capacity of these three cultivars under conditions of environmental stress.
'Parthenon' showed equal productivity and nutritional composition to 'Nubia', whereas 'Naxos' presented in general the best results when compared to 'Nubia' and 'Parthenon'. For phenolic compounds 'Nubia' presented the highest contents, although 'Naxos' seemed better adapted to saline stress conditions, as suggested by the lowest degree of variation in the contents of healthy phytochemicals, including phenolic compounds, when grown under such conditions.
'Naxos' broccoli performed best and is a suitable candidate to replace 'Nubia' for marketable, nutritive and phytochemical quality, especially in areas of production under adverse conditions as found in Mediterranean southeast Spain (semiarid climate with saline irrigation water).
由于对其生物活性成分和营养价值的兴趣，西兰花在全球的消费稳步增长。在当前生产地区（恶劣的环境条件和咸水灌溉）下，需要建立新型西兰花品种以保持其食用和全年供应市场的物理和营养品质。新引入的品种“纳克索斯”和“帕特农”已被选为替代目前表现不佳的“努比亚”品种的潜在候选品种。我们旨在比较这三个品种在环境胁迫下的物理和植物化学品质（硫代葡萄糖苷、羟基肉桂酸、类黄酮、维生素 C 和矿物质）以及体外抗氧化能力。
“帕特农”的生产力和营养成分与“努比亚”相当，而“纳克索斯”与“努比亚”和“帕特农”相比总体上表现最佳。就酚类化合物而言，“努比亚”的含量最高，尽管“纳克索斯”似乎更能适应咸水胁迫条件，因为在这种条件下，包括酚类化合物在内的健康植物化学物质的含量变化最小。
“纳克索斯”西兰花表现最佳，是替代“努比亚”的合适候选品种，尤其适合在西班牙东南部地中海地区（半干旱气候和咸水灌溉）等不利生产条件下的市场、营养和植物化学品质。
