芹菜是一种两年生作物，因其茎、叶和种子而在全球各地种植，以其独特的风味和浓郁的味道而闻名。文献报道了新鲜和干芹菜及其精油的各种提取方法，检查了这种作物的香气特征，并证明其挥发性成分是由品种、季节、地理位置和农艺实践等变量决定的。这项研究调查了在英国同一地点两年（2018 年和 2020 年）种植的八种芹菜基因型的挥发性和感官特征。采用固相微萃取和气相色谱-质谱法测定这些基因型中存在的挥发性化合物，并使用经过培训的小组进行感官评估，以评估新鲜芹菜的感官特征。观察到挥发性成分和感官特征的显着差异（p < 0.05），并受到基因型和收获年份的影响。多年来，两种基因型表现出相似的香气成分和感官特征。 2018 年收获的芹菜样品的气温比 2020 年高得多，其倍半萜烯和苯酞的比例较高，我们假设较高比例的产生是对热应激的反应。研究基因型与环境之间的关系将为指导种植者如何持续生产更高质量的作物提供清晰的信息。
Apium graveolens is a biennial crop grown across the globe for its stalks, leaves and seed and is known for its distinct flavour and strong taste. Various extraction methods on fresh and dried celery and its essential oil are reported in the literature examining the aroma profile of this crop and demonstrating that its volatile composition is determined by variables including cultivar, season, geographical location and agronomic practices. This study investigated the volatile and sensory profile of eight celery genotypes grown over two years (2018 and 2020) in the same location in the UK. Solid-phase-micro-extraction followed by gas chromatography-mass spectrometry were used to determine the volatile compounds present in these genotypes and sensory evaluation using a trained panel to assess the sensory profile of fresh celery. Significant differences (p < 0.05) in the volatile composition and sensory profile were observed and influenced by both genotype and harvest year. Two genotypes exhibited similar aroma composition and sensory profile between the years. Celery samples harvested in 2018, which possessed air temperatures that were considerably warmer than in 2020, exhibited higher proportions of sesquiterpenes and phthalides and we hypothesise that the higher proportions were generated as a response to heat stress. Studying the relationship between the genotype and the environment will provide clear information to guide growers in how to consistently produce a higher quality crop.
