This is true but doing fire treatment at home is tricky business; it's easy
to get it too hot and zap the seed. A nurseryman I know soaks the seed in
gasoline for about 10 minutes and gets very good germination -- evidently it
is not the heat that breaks seed dormancy but rather the volatiles that are
released during burning in habitat. I don't know if other substances might
work just as well as gasoline but that seems to work well for him.
