I have grown persimmon seedlings in the PVC pipe "containers", and it works very well.
I germinated both some apple and pear seeds from a neighbor's farm old fruit trees (they are at least 40-50 years old)- I have no idea of what type they are, but they germinated pretty well (about 40-50% germination). Unfortunately, I only put plastic tree protectors around the ones I set out last year instead of some of my spare wire tomato cages and the deer ate them down to the main "trunk". I need to go back and try to find some fruit that the deer missed and grow up another batch to set out next fall.
