Those 2016 posts were only the newer ones. Some go back to 2006, so the theory goes back more than 10 years. Notice that there is anecdotal success with Albuca spp., but it's not know how well the process might work with other plants. A friend sent me pollen from her Turkish hazelnut so I can pollinate mine, but I am also going to try microwaving. I've asked around and it seems no one has tried it on trees before.
