Flowering phenology influences seed production and outcrossing rate in populations of an alpine snowbed shrub Phyllodoce aleutica: effects of pollinators and self-incompatibility

摘要

Background and AimsBecause of differences in snowmelt time, the reproductive phenologies of alpine plants are highly variable among local populations, and there is large variation in seed set across populations. Temporal variation in pollinator availability during the season may be a major factor affecting not only seed production but also outcrossing rate of alpine plants.
