RE: germinating Chorizema
Hot water treatment normally cracks a water impervious outer shell. The
same effect can usually be had from nicking the seed coat (scarification)
which is what they describe with the sand paper. I think I read somewhere,
Deno?, that some African and/or Austrailian plants triggered to germination
by fire MAY benefit from potassium nitrate, but I don't think there is any
hard research to back this up.
