Influence of sex-organ positions on pollen transfer and self-interference in plants with stylar polymorphisms: An experimental approach using three-dimensional printed flowers

Heterostylous plants are characterized by the reciprocal placement of stigmas and anthers in the floral morphs. Darwin proposed that this arrangement increases the proficiency of disassortative (intermorph) pollen transfer. The floral polymorphism may also function to avoid gamete wastage by reducing interference between sex organs. Distylous populations consist of two morphs: the long-styled morph with stigmas above anthers and the short-styled morph with stigmas below anthers. A related floral polymorphism – stigma-height dimorphism – involves floral morphs that differ in stigma-height but not anther position.
We used three-dimensional printed artificial flowers, with attached styles and anthers from glasshouse-grown Petunia grandiflora, to investigate whether sex-organ positioning simulating distyly and two forms of stigma-height dimorphism influence patterns of pollen transfer. Artificial flowers were arranged in flight cages and pollen transfer within and among flowers was mediated..., , # Influence of sex-organ positions on pollen transfer and self-interference in plants with stylar polymorphisms: An experimental approach using three-dimensional printed flowers

## Description of the data and file structure

### Files and variables

This dataset and accompanying R scripts support an analysis of pollination efficiency in experimental arrays simulating different types of stylar polymorphisms (e.g., heterostyly, stylar dimorphism). In the experiments, some flowers were used as pollen donors and others as pollen recipients. Several variables were compared across different \"treatments\" (types of polymorphism), including:

* The time bees spent per flower (handling time)
* The amount of pollen deposited on stigmas and styles of recipient flowers
* The amount of pollen remaining in the anthers of donor flowers

The study examines how pollinator behavior affects reproductive metrics using generalized linear model...,
