Nectar robbing by bees affects the reproductive fitness of the distylous plant Tirpitzia sinensis (Linaceae)

Nectar robbing can affect plant reproductive success directly by influencing female and male fitness, and indirectly by affecting pollinator behavior. Flowers have morphological and chemical features that may protect them from nectar robbers. Previous studies on nectar robbing have focused mainly on homotypic plants. It remains unclear how nectar robbing affects the reproductive success of distylous plants, and whether defense strategies of two morphs are different. Nectar robbing rates on the long- and short- styled morph (L-morph, S-morph) of the distylous Tirpitzia sinensis were investigated. We compared floral traits, the temporal pattern of change in nectar volume and sugar concentration, nectar secondary metabolites and sugar composition between robbed and unrobbed flowers of two morphs. We tested direct effects of nectar robbing on female and male components of plant fitness and the indirect effects of nectar robbing via pollinators. Nectar robbing rates did not differ between th..., We collected the floral traits, the temporal pattern of change in nectar volume and sugar concentration, bee nectar robbing behavior, hawkmoth preference, female fitness, male fitness, nectar samples in the field. The nectar secondary metabolites and sugar composition were analyzed with Ultra Performance Liquid Chromatography-Quadrupole/time-of-flight mass spectrometers and High performance Liquid Chromatography respectively., , This README file was generated on 2023-10-12 by Xiaoyue Wang.
