Regulation of reproductive success in the biennial plant, Hydrophyllum appendiculatum

The major goal of this study was to determine the relative importance of genetic and environmental sources of variation in reproductive success in Hydrophyllum appendiculatum (Hydrophyllaceae), a biennial, self-compatible, outcrossing, insect-pollinated, forest understory herb. Observations conducted in two populations over three flowering seasons (1987-1989) revealed that survival, flower production, and seed production varied spatially and temporally. While some of this variance was probably due to rainfall patterns, seed production was negatively affected by an unidentified pathogen and a weevil that consumed flowers and developing seeds.
