花的颜色在与花生物学和传粉者行为相关的各个领域中都是非常重要的。然而,人类对花的颜色的主观判断可能是不准确的,并且与花的传粉者的生态和视觉无关。为了获得关于花的颜色的准确、详细的信息,应该使用感兴趣的花的全反射光谱,而不是依赖于这样的人类评估。开发了花卉反射率数据库(FRED),以向研究人员提供广泛的此类数据收集。它可以在http://www.reflectance.co.uk.上免费获得该数据库允许用户下载从世界各地收集的花卉品种的光谱反射率数据。例如,它们可以用来模拟传粉者视觉和植物信号之间的相互作用,或者分析不同生境中的花的颜色。该数据库包含根据广泛使用的蜜蜂颜色空间模型计算花的颜色轨迹的功能、光谱的反射率图以及在蜜蜂颜色空间中搜索具有相似颜色的花的选项。花卉反射率数据库是一个有价值的新工具,研究人员对花卉的颜色及其与传粉者颜色视觉的关系感兴趣,它包含了大量花卉物种的原始光谱反射率数据。
Flower colour is of great importance in various fields relating to floral biology and pollinator behaviour. However, subjective human judgements of flower colour may be inaccurate and are irrelevant to the ecology and vision of the flower's pollinators. For precise, detailed information about the colours of flowers, a full reflectance spectrum for the flower of interest should be used rather than relying on such human assessments. The Floral Reflectance Database (FReD) has been developed to make an extensive collection of such data available to researchers. It is freely available at http://www.reflectance.co.uk. The database allows users to download spectral reflectance data for flower species collected from all over the world. These could, for example, be used in modelling interactions between pollinator vision and plant signals, or analyses of flower colours in various habitats. The database contains functions for calculating flower colour loci according to widely-used models of bee colour space, reflectance graphs of the spectra and an option to search for flowers with similar colours in bee colour space. The Floral Reflectance Database is a valuable new tool for researchers interested in the colours of flowers and their association with pollinator colour vision, containing raw spectral reflectance data for a large number of flower species.
