Ed/Bob- While done on a smaller scale (so we could bring trees into lab), I recall taking a lab class called Stem Analysis (hmm, in 1982 methinks), where we did just as Ed's described below...we took cookies out of the tree at mid-whorl and at mid 'span', coded them, then measured them under binocularscopes. There's a lot of studies out there on this kind of inquiry. -Don From: [email protected] To: [email protected] Subject: [ENTS] Re: Radial versus volume growth Date: Wed, 14 Jan 2009 19:04:13 -0500
Bob, I do see the approach you are taking. I am considering it. The previous notes were just ideas off the top of my head on the subject. The basic premise you are looking at is that tree A over time will change to be the height, girth, and form of tree B over time. (Actually it is the converse of that arguing tree B was the same size, shape and girth as form as A at some point in the past.) On an individual basis that is an unlikely proposition, but as a statistical set of average trees, the arguments would appear to be valid. If you had a big tree that was cut down. And you were able to slice the trunk at various heights. You could determine the the girth at a given point at a given time at a given height by counting backwards from the outermost ring. You could determine at what age the tree reached the height of that cut, and you could reconstruct the form of a particular tree and its volume at any give point in time. The closer the slices together, the more detail you would have and the better you could reconstruct the tree in the past.
