花香的主要功能是吸引和引导传粉者，但也是观赏植物产业中的一个重要特征。一些研究已经考虑了花瓶生命期花香的化学评价，但很少有研究考虑了这一特性的感官分析，这是观赏植物销售的一个非常重要的品质性状。本研究的重点是评估三种具有高经济价值的芳香切花：百合、菊花和小苍兰。80个个体被纳入感官分析，在那里对花香的喜好和强度属性进行了评估。采用气相色谱-质谱联用（GC-MS）分析了花香的成分。与菊花相比，东方百合和小苍兰的花香被认为更强烈。共检测到28种挥发性化合物，其中单萜类-蒎烯（40.7 +/- 1.8 μ g.L-1）、-顺式-辛烯（5552 +/- 990 μ g.L-1）和芳樟醇（11800 +/- 220 μ g.L-1）是菊花、百合和小苍兰的主要挥发性有机化合物。本研究结果证实，挥发性化合物的浓度和丰度与人类对花香的感知没有直接关系。
The main function of floral scent is to attract and guide pollinators, but it is also an important character in the ornamental plant industry. Several studies have considered the chemical evaluation of floral scent during vase life, but only a few have considered sensorial analysis of this character, which is a very important quality trait for the marketing of ornamental plants. This study focused on assessing the floral scent of three fragrant cut flowers of high economic importance: Lilium, chrysanthemum, and freesia. Eighty individuals were included in a sensorial analysis where the attributes of floral scent liking and intensity were evaluated. The composition of the floral scent was analyzed through the collection of headspace followed by gas chromatography-mass spectrometry (GC-MS). The floral scents of oriental lily and freesia were perceived as more intense, compared to chrysanthemum. A total of 28 volatile compounds were detected and the monoterpenes beta-pinene (40.7 +/- 1.8 mu g.L-1), beta-cis-ocimene (5552 +/- 990 mu g.L-1), and linalool (11,800 +/- 220 mu g.L-1) were the major volatile organic compounds (VOCs) present in chrysanthemum, lilium, and freesia, respectively. The results presented in this study confirm that the concentration and abundance of volatile compounds is not directly related to the human perception of floral scent.
