@Roosterlorn Lorn, I haven't tried this-- Judith gave me a recipe sometime back... boric acid comes to mind. Anyway I forgot the recipe! Joe, I think Lorn is talking about germinating the pollen to view the growth of pollen tubes under a microscope. It is an indication of whether the pollen is good or not and also can give information on the length of the pollen tubes... too short then it won't reach its destination!
