Nectar chemistry is not only a plant's affair: floral visitors affect nectar sugar and amino acid composition

<p>This dataset contains data used in the analyses performed in the article entitled &quot;Nectar chemistry is not only a plant&rsquo;s affair: floral visitors affect nectar sugar and amino acid composition&quot;. The Excel file contains three sheets. &#39;Raw data&#39; contains concentration of sugars, amino acids, pollen grains and yeast cells measured in several flowers and plants of <em>Gentiana lutea</em> subsp. <em>symphyandra</em>, belonging to different experimental treatments. &#39;Amino acid diversity&#39; contains the concentration of specific protein and non-protein amino acids found in a subset of the above mentioned flowers. &#39;Pollen suspension test&#39; contains the concentration of the same amino acids found in nectar after suspension of pollen of <em>G. lutea</em> at different time intervals (0, 1, 4, and 24 hours).</p>
