Other claims from this paper (9)
- Intervention effect In a factorial design, progeny type had no significant effect on seed mass or days to germination in Silene vulgaris.
- Association Seeds differed significantly by maternal parent for all seed and seedling variables.
- Intervention effect A higher proportion of seeds from outcrossed individuals germinated than from self-fertilization.
- Observation Differences among offspring appeared during germination rather than later development.
- Association Seed mass, cross type and sex of the maternal parent all significantly affected the likelihood of germination.
- Observation Seed mass, cross type and maternal sex had decreasing predictive power for germination, in that order.
- Mechanism Inbreeding depression in Silene vulgaris may help maintain gynodioecy.
- Mechanism Pleiotropic effects of nuclear and cytoplasmic genes for sex expression may affect fitness and the maintenance of females.
- Observation One-way ANOVA by progeny type showed statistically discernable differences among progeny from different cross types, which the authors attribute to a reduced error term and biased F ratios.
