These dichogamous mechanisms would clearly serve to restrict self-pollination.
Dioecious species that evolved via the gynodioecy route typically are not dichogamous (Cruden, 1988); they do not have preexisting devices for the avoidance of inbreeding.
Nevertheless, dioecious species displaying spatial segregation of the sexes are far more likely to have perfect-flowered dichogamous (protogynous, and therefore already outbreeding) relatives than dioecious species that do not display spatial segregation of the sexes.
