对三十种开花植物的花蜜氨基酸组成进行了分析。高效液相色谱 (HPLC) 与 AccQtag 衍生化结合使用，可产生准确且精确的数据。对于任何一个物种，氨基酸的总浓度变化很大（平均变异系数为 0.65），但组成的变化要小得多（单个物种样品之间的平均相关性为 0.85）。单个氨基酸的绝对浓度比相对丰度变化更大（变异系数分别为 0.98 和 0.77；N = 544，t = 16.98。P < 0.001），当氨基酸仅以较小的相对丰度出现时（
Thirty species of flowering plants were analyzed for floral nectar amino acid composition. High-performance liquid chromatography (HPLC) was used in conjunction with AccQtag derivatization to produce accurate and precise data. For any one species, the total concentration of amino acids varies greatly (average coefficient of variation 0.65), but composition is much less variable (average correlation among samples from a single species 0.85). Absolute concentration of individual amino acids is much more variable than the relative abundance (coefficients of variation 0.98 and 0.77, respectively; N = 544, t = 16.98. P < 0.001), When amino acids that occur in only small relative abundance (
