摘要: Inbreeding depression is a key factor influencing mating system evolution in plants, but current understanding of its relationship with selfing rate limited by sampling bias few estimates for self-incompatible species. We quantified inbreeding (δ) over two growing seasons populations the perennial herb Arabidopsis lyrata ssp. petraea Scandinavia. was strong and similar magnitude both populations. overall fitness across (the product number seeds, offspring viability, biomass) 81% 78% Chlorophyll deficiency accounted seedling mortality treatment, not observed among resulting from outcrossing. The reduction early viability late quantitative traits suggests that due to deleterious alleles large small effect, experience selection against loss self-incompatibility. A review available suggested tends be stronger than self-compatible highly outcrossing species, implying undersampling taxa may between depression.
