Data from: The presence and strength of post-pollination barriers in an orchid lineage that lacks pollinator specialization

This dataset contains the results of manual pollination experiments
(intraspecific, interspecific, and double pollinations) among four species
of the orchid genus Anacamptis: A. laxiflora (LAX), A. morio (MOR), A.
papilionacea (PAP), and A. fragrans (FRA). Data were collected during
controlled pollinations performed between 2020 and 2022. The dataset is
organized into eight spreadsheet tabs, grouped by the pollen recipient
species. For each species, the sheets include results on fruit set and the
percentage of embryonated seeds for each pollination combination. These
data were used to evaluate the strength and asymmetry of post-pollination
barriers and to explore their contribution to reproductive isolation in an
orchid lineage characterized by low pollinator specialization. The dataset
supports the findings reported in the manuscript “The interplay of early
and late post-pollination pre-zygotic barriers in an orchid lineage with
low pre-pollination isolation” (Masullo et al., submitted).
