通过评估从信号花到感知传粉者的信息传递，量化了花的着色和花的颜色视觉之间的进化调谐。对180个被子植物花朵反射光谱的分析表明，尖锐的台阶恰好发生在传粉者对光谱差异最敏感的波长处。简单的模型计算确定了最佳的一组3光谱感光器类型的感知差值的基础上的花朵颜色信号的歧视。结果表明，良好的协议与电生理学的特点，在40种的Hytera的光感受器。
The evolutionary tuning between floral colouration and the colour vision of flower-visiting Hymenoptera is quantified by evaluating the informational transfer from the signalling flower to the perceiving pollinator. The analysis of 180 spectral reflection spectra of angiosperm blossoms reveals that sharp steps occur precisely at those wavelengths where the pollinators are most sensitive to spectral differences. Straightforward model calculations determine the optimal set of 3 spectral photoreceptor types for discrimination of floral colour signals on the basis of perceptual difference values. The results show good agreement with the sets of photoreceptors characterized electrophysiologically in 40 species of Hymenoptera.
