Intervention effect Fruit fermentation was effective for removing the mesocarp without harming the embryo.
Intervention effect Manual mesocarp removal was effective.
Intervention effect Digestion in 32% hydrochloric acid completely inhibited germination.
Method / resource Cracking the endocarp with pliers followed by manual seed removal was the most efficient seed extraction method.
Intervention effect Germination was completely inhibited when less than half of the endocarp was removed.
Intervention effect Disinfestation and aseptic germination controlled microbial contamination of fruits and seeds.
Mechanism The authors attribute dormancy chiefly to physical restriction of the embryo by the hard endocarp.
