Propagation

Seed - the seedcoat is so hard that pre-treatment with boiling water may not be sufficient to break the dormancy. Furthermore, the large aril around the seed delays germination and must be removed. By using a sharp knife, it is possible to cut off the aril together with a small chip of the seedcoat but care must be taken not to damage the radicle. If the seed coat is not scarified while removing the aril, the seed should be nicked at the opposite end. After cutting, the seeds are soaked in water for 12 hours before sowing[
