I don't know if you know that already, but you can germinate your palm seeds more quickly with the following method.Put a sandpaper on a table.Since theseeds are big enough keep one each time in your fingers.Then try to scratch one tip of the seed scrubing it on the sandpaper until the cotyledons start to appear.You have to do it diligently so as to avoid hurting the embryo inside the seed.
In this way your seeds are going to absorb water faster and the enzymes inside them will get them germinated immediately, without waiting for the wood outside the seed to decompose.

Good luck
