AbstractIn a study of the effects of distance between individuals on reproduction and fitness, pollen distance from the maternal plant had no effect on seed mass or first year stem length for either Eupatorium resinosum or Eupatorium perfoliatum. However, seedling size and reproductive success in the second growing season increased with pollen distance from maternal plant. The study found evidence for hybrid vigor when plants are pollinated by pollen from outside populations in both study species and evidence for inbreeding depression for pollinations occurring at short distances in the rare E. resinosum.
