Other claims from this paper (14)
- Observation Inbreeding depression was largest for seed maturation.
- Observation Seedset in open-pollinated strobili was about four times higher than in selfed strobili.
- Observation Inbreeding depression in postgermination survival was high.
- Observation No significant difference in tree height from inbreeding after 23 years.
- Observation No significant difference in flowering from inbreeding after 23 years.
- Observation Cumulative inbreeding depression was high.
- Observation Cumulative inbreeding depression differed significantly among maternal families.
- Association Inbreeding depression magnitude among maternal parents was not significantly correlated between early and later life stages.
- Mechanism The genetic basis of inbreeding depression is suggested to vary across the life cycle.
- Mechanism Size-specific mortality is suggested to cause the decrease in inbreeding depression estimates for height.
- Observation Inbreeding depression estimates for height decreased over time.
- Observation Scots pine exhibits high levels of inbreeding depression during both early and later life stages.
- Mechanism Self-fertilization is argued to be inefficient in purging the genetic load in Scots pine.
- Observation The result is an effectively random mating outcrossing population.
