对32种不同授粉系统植物花蜜中的氨基酸和糖进行了定量分析和比较。糖和氨基酸浓度之间没有相关性。氨基酸的组成和浓度与进化进程没有相关性，也与传粉系统没有直接关系。然而，较高的糖浓度往往与更先进的形态特征。来自刺穿或损坏的花或被花粉污染的花蜜的氨基酸组成表现出改变和增加。脯氨酸的存在可能表明这种花粉污染。大多数传粉动物的能量需求依赖于花蜜，但存在无数替代的氨基酸和蛋白质来源。
Individual amino acids and sugars from flower nectar of 32 plant species with different pollination systems were quantified and compared. There is no correlation between sugar and amino acid concentration. There is no correlation between composition and concentration of amino acids and evolutionary advancement, nor any direct relation with pollination systems. However, higher sugar concentrations are often linked with more advanced morphological characters. Nectars from pierced or damaged flowers or nectars contaminated with pollen exhibit modifications and increases in amino acid composition. The presence of proline probably indicates such pollen contamination. Most pollinating animals depend on flower nectar in their energetic requirements, yet innumerable alternative amino acid and protein sources exist.
