Re: [nafex] large tree renovation

Title: Re: [nafex] large tree renovation
So-called "graft hybrids" do happen, but they are rare.  One that is reasonably well verified is "Pyronia veitchii" which is a graft hybrid of Pyrus and Cydonia, supposedly having arisen as a shoot from the graft union of pear and quuince.  The plant is indeed a mix of both species.  
This is a very rare situation, though, so it's unlikely the seed grafting would work much of the time.  As you say, though, it's pretty hard to verify it when it's between two very similar individuals.  You would almost have to have "marker" traits in each seedling to verify the "hybrid".  Something like dark red shoots in one and green in the other, with the hybrid having light red shoots.

also dabbled at splicing seeds as a way of crossing varieties. I wonder
if their 'success' in this was actually the germ growing and it's
differences not being due to the splicing, in other words, that the
result would have been the same without splicing the seed. Does anyone
know if there is any validation for this? It would seem pretty far
fetched in a time not so technologically advanced, and if it had worked,
wouldn't we still be playing with the process?
