在许多开花植物中，花的气味是一种重要的访客特征，在吸引传粉者和/或吸引食草动物方面起着重要作用。开花植物从雌雄同体到雌雄异体的进化通常伴随着花香的两性二形现象。本研究对亚雌雄异株灌木泛亚（Eurya japonica Thunb）不同性别形态的花香进行了研究。采用动态顶空法采集，并通过气相色谱-质谱（GC-MS）评估性别和时间变化。两种挥发物α -蒎烯和芳樟醇被鉴定为雌性、雌雄同体和雄性花香味的主要成分。与雌性或雌雄同体相比，雄性散发出更多的花香，尤其是α -蒎烯。当花进入衰老时，雄性发出的花香通常会减少，而雌性或雌雄同体发出的花香则没有显著差异。本研究提供的亚雌雄异株花香味的种内变异有助于更好地了解花香味的两性二态性。
In many flowering plants, floral scents are a significant trait for visitors, playing an important role in attracting pollinators and/or detracting herbivores. The evolution of flowering plants from hermaphroditism to dioecy is often accompanied by sexual dimorphism in floral scent. In this study, floral scents emitted by different sexual morphs of the subdioecious shrub Eurya japonica Thunb. were collected using a dynamic headspace method, and sexual and temporal variations were evaluated by gas chromatography–mass spectrometry (GC–MS). Two volatiles, α‐pinene and linalool, were identified as the major components of floral scents in females, hermaphrodites, and males. The males emit higher amounts of floral scents, particularly α‐pinene, compared to females or hermaphrodites. Floral scents emitted by males generally decrease as flowers enter senescence, whereas those from females or hermaphrodites do not significantly differ. Intraspecific variations in floral scents of subdioecious species provided by this study would contribute to better understanding of sexual dimorphism in floral scent.
