title: How does population outcrossing rate influence seed quality? Evidence from a 58-year-old seed tree stand of Pinus massoniana
abstract: Abstract Inbreeding is thought to be a key adverse factor impacting the genetic quality of seeds in seed production populations and the inbreeding degree (i.e., selfing or outcrossing rate) of seed production populations have been extensively assessed through mating system analysis. The depression effect of inbreeding on seed quality traits in seed production populations under open-pollination conditions has not yet been clearly described. In this study, the open-pollinated seeds were collected
