Paper Abstract Premise of research. Sex allocation theory considers that, given limited resources, a trade-off must exist between allocations to competing functions, such as accessory and primary sexual organs, or between allocations to primary male and female sexual organs. However, phenotypic and genotypic correlations between floral components have often been found to be positive. A view of resource allocation from a phenotypic-integration perspective could shed light on these apparently paradoxical results. Resource allocation, and not only floral metric traits, can also be significantly integrated because of genetic or developmental constraints or functional contribution to offspring production. We describe the allocation of resources to inflorescence components and assess for the first time whether resources can also be phenotypically integrated in Tussilago farfara L. (Asteraceae), a species with inflorescences functioning as pollination units.
