Genetic and environmental factors affecting reproductive variation in Allium vineale

摘要: Traits related to allocation of resources sexual and asexual reproduction, together with seed production, were-scored on Allium vineale plants sampled from five sites in southern Sweden during a period 4 years. In addition, random amplified polymorphic DNA (RAPD) fingerprinting the allowed identification genets. Integration genetic phenotypic data field greenhouse provided for analysis among-year, among-site, among-genet variance components. These components were taken represent influences short-term environmental changes, persistent site divergence, within-site genet differences, respectively. It was shown that differences among genets explained large part variation traits, whereas among-year had larger influence production. Together, results support conclusions recent model evolution mixed reproductive systems, predicts stable balance between reproduction because annual fluctuations fecundity through two modes. (Less)
