Ed: You say " I can't address the Ontario materials you refer to as I have not seen them."
Well, I tried to reconstruct my earch to find the article again, but have not found it yet. But in the process I have found a large number of articles on white pine genetics. In the summaries I have found all kinds of tidbits that may bear on the question. Some of these could seem to support the idea I reported earlier, others I could understand to contradict it. And some of these studies include terminology and methodology I simply do not understand. None of the studies I have come across so far focus directly on genetic factors that affect height growth. At this point I guess I will have to conclude that any serious discussion of the genetic diversity of white pine, especially in the context of our discussion here, is something I should not attempt. --Gaines -------------------------------------------
