| Parkia biglobosa |
This paper
presents results from a trial with controlled self- and cross-pollination of the
semi-domesticated fruit tree, Parkia
biglobosa (Fabaceae). We used eight trees acting as fathers and mothers in
a diallelic cross.
Due to
over-exploitation, low regeneration and reduced rainfall the density of P. biglobosa trees is declining in the
landscapes in West Africa, and we expect more self-pollination because of
increased distances among trees. Since P.
biglobosa is known as a mostly outbreeding species, we wanted to reveal a
potential effect of increased selfing by comparing fruit set and seed
germination after self- and cross-pollination.
