摘要

香水花为专门的传粉者,即雄蜂提供化学物质作为资源。该系统在至少15个新热带被子植物科中有记录,包括凤梨属的各种。本文研究了隐花(Cryptanthus bahianus)的传粉和化学生态,强调了花信号在吸引传粉者中的可能作用。在巴西东北部的一个巴hianus种群中,我们描述了开花情况,确定了繁殖系统,测量了花蜜的体积和浓度,并表征了主要的花线索,如形态、颜色和花香。此外,我们还研究了花与访问者之间的相互作用。bahianus是一种雌雄同株的植物,每天开花,从早上5点开始,这时已经有花蜜了。白色管状花分泌花蜜9±2.8 μL,平均浓度为18.7%±6.96%。香味中主要成分为苯甲醇、(Z)-和(E)-3-甲基-4-十烯酸,占总香气的95.49%。访花者包括雄性和雌性的eugine蜜蜂,它们只寻找花蜜。C. bahianus提供花蜜,并最终提供花粉作为花的奖励,这与在该属的其他三种有香水花的物种中发现的模式相反。对C. bahianus花香味的化学分析没有发现共酚的存在,共酚是一种半挥发性二萜,由C. burle-maxii花产生,并由其雄性eugineine传粉者寻找。C. bahianus在隐花属系统发育中处于基础位置的事实表明,花蜜是隐花属的一种多形性特征,香水花可能是从花蜜进化而来的。

期刊介绍: Plant Biology is an international journal of broad scope bringing together the different subdisciplines, such as physiology, molecular biology, cell biology, development, genetics, systematics, ecology, evolution, ecophysiology, plant-microbe interactions, and mycology. Plant Biology publishes original problem-oriented full-length research papers, short research papers, and review articles. Discussion of hot topics and provocative opinion articles are published under the heading Acute Views. From a multidisciplinary perspective, Plant Biology will provide a platform for publication, information and debate, encompassing all areas which fall within the scope of plant science.
