Cover Story: Floral nectar is produced in nectaries and contains sugars and other compounds, including amino acids, but little is known about their function and origin in nectar. To gain further insight, the concentration of amino acids and other compounds, as well as the enzyme activity (AlaAT and GS), in nectar, nectaries, and leaves were analyzed in 30 Pitcairnia species. The presence of almost all amino acids in nectar is mainly due to their transport in the phloem to the nectaries. Some amino acids must additionally be produced de novo in the nectaries, like alanine in some Pitcairnia species. Species with reddish flowers or bracts have increased concentrations of alanine and glutamine in the nectar, so they are likely pollinated by hummingbirds, passerine birds, or butterflies.
