花香是开花植物性状库中的重要组成部分，用于吸引和操纵传粉者。尽管在过去的几十年里，关于花释放的化学物质的研究取得了进展，但我们对开花植物及其传粉者之间的化学交流的理解仍然存在很大差距。我们用化学分析方法分析了瓜拉那(Paullinia cupana，无患科Paullinia cupana)的花香，并用田间行为分析方法确定了这种气味对夜间蜜蜂传粉者的吸引力。还对引诱蜜蜂的花粉载量进行了分析。瓜拉那的花序在白天和晚上都发出强烈的气味，白天和晚上的气味有一些半定量的差异。含有一些已鉴定的花香成分的合成香味混合物，包括最丰富的芳樟醇和(E)-β-罗勒烯，成功地吸引了夜间授粉的大眼蜂。花粉分析显示，许多被吸引的蜜蜂身上都有以前访问过瓜拉那花的花粉颗粒。总体而言，我们的数据显示，瓜拉花通过其强烈的气味吸引夜间蜜蜂访客，并表明这种植物与其传粉者之间的化学交流是这种重要经济植物物种作物生产的关键组成部分。
Floral scent is an important component of the trait repertoire of flowering plants, which is used to attract and manipulate pollinators. Despite advances during the last decades about the chemicals released by flowers, there is still a large gap in our understanding of chemical communication between flowering plants and their pollinators. We analyzed floral scents of guarana (Paullinia cupana, Sapindaceae), an economically important plant of the Amazon, using chemical analytical approaches, and determined the attractiveness of the scent to its nocturnal bee pollinators using behavioral assays in the field. Pollen loads of attracted bees were also analyzed. Inflorescences of guarana emit strong scents, both during day and at night, with some semi-quantitative differences between day- and night-time scents. Synthetic scent mixtures containing some of the identified floral scent components, including the most abundant ones, i.e., linalool and (E)-β-ocimene, successfully attracted the nocturnal Megalopta bee pollinators. Pollen analyses revealed that many of the attracted bees had pollen grains from previous visits to guarana flowers on their bodies. Overall, our data show that guarana flowers attract nocturnal bee visitors by their strong scents and suggest that the chemical communication between this plant and its pollinators is a key component in crop production of this economically important plant species.
