Other claims from this paper (6)
- Intervention effect In the nursery test, selfing decreased the means of size traits in lodgepole pine seedlings relative to cross families.
- Intervention effect Selfing retarded phenological development in lodgepole pine seedlings relative to cross families.
- Intervention effect Selfing increased variance among families within populations, the coefficient of within-family variance and within-family skewness in lodgepole pine.
- Intervention effect The selfing depression of mean values was moderately less in population A than in populations B + C.
- Intervention effect The selfing inflation of within-plot variation was much less in population A than in populations B + C.
- Observation Even with purging, population A retained a large inbreeding depression in both embryonic and seedling traits.
