Steve, I have no real evidence that any of these work, but I've heard them. 1) Saliva as mentioned by others 2) Dip pollinia in orange juice then apply. 3) Pollinate with two applications per flower, one: its own pollen, two: some other totally unrelated species that is genetically incompatible. 4) Pollinate with two applications per flower, one: its own pollen, two: some other related species that is genetically compatible, but different enough that the offspring in the flask will be obviously not the same species, but clearly a hybrid -- then sort plants if any of the "self" pollen was successful. 3 & 4 presumably could work if the trouble is that a capsule won't stay on the plant because the pollen isn't foreign enough. By "inspiring" the capsule to say on, the self-pollen has a chance to grow into the ovary. This will NOT help if the trouble is at the egg itself. -Troy > The question: I have read stories about tricks for overcoming, or at > least reducing, self-incompatibility - things like using pollen from old > flowers on new flowers (or the other way around), etc. But never within > the orchid family. Does anyone have any advice?
