Under noiseless experimental conditions, sugar concentration of secreted floral nectar may increase after flower exposure to nearby sounds of pollinator flight (Veits et al. 2019). However, we reject the argument that this represents adaptive plant behaviour, and consider that the appealing analogy between a flower and human ear is unjustified.

花蜜的变化不太可能对传粉媒介的飞行声音产生适应性反应。

在无噪音的实验条件下，花朵暴露于传粉媒介附近的飞行声中后，分泌的花蜜的糖浓度可能会增加（Veits等人2019）。但是，我们拒绝说这代表了植物的适应性行为，并且认为花和人耳之间的吸引人的类比是不合理的。
