Fig. 2From: Ancillary polymorphic floral traits between two morphs adaptive to hawkmoth pollination in distylous plant Tirpitzia sinensis (Linaceae)Comparison of nectar volume, sugar concentration (mean ± SE) of L- and S-morphs between day and night in T. sinensis (A) and comparison of fructose, glucose and sucrose composition (mean ± SE) in the L- and S-morph nectar of T. sinensis (B). Bars that share the same letters are not significantly different between treatments. Numbers in the bar graph represent the sample sizeBack to article page
