Some have a waxy coating which must be removed before moisture
will penetrate. In nature this is presumably achieved by passing through
an animal's gut. Soaking with dilute detergent may be effective.

As will the ensuing 30 minute soak in mild bleach. Wax is not a
primary germination inhibitor. It serves to prevent dessication of
relatively thin coated seeds. Seeds that are 'held back' through a
waxy coating. germinate very readily when it is removed. Hypochlorite
ensures the eradication of bacteria that can quickly destroy embryo
tissue and is generally a better option.

My understanding is that wax prevents gemination primarily by
preventing the absorption of water - so any method that removes
it over even part of the coat will work. Including both of those
and scarification.

Don't forget the fungi - bleach will kill at least some of them,
as well as bacteria.
