Other claims from this paper (10)
- Intervention effect Selfing reduced seed maturation relative to open pollination.
- Observation Selfed progeny had high postgermination survival depression through age 23.
- Observation Height after 23 years did not differ significantly by progeny type.
- Observation Flowering after 23 years did not differ significantly by progeny type.
- Observation Cumulative inbreeding depression was high.
- Observation Cumulative inbreeding depression varied significantly among maternal families.
- Association Early and later inbreeding depression were not significantly correlated among maternal parents.
- Observation Progeny size differences diminished over time.
- Mechanism Authors argue that self-fertilization inefficiently purges genetic load in Scots pine because selfed individuals are nearly entirely lost.
- Mechanism Authors infer that the population is effectively randomly mating and outcrossing.
