I'm interested in this work - was it ever published?  It seems to support
the idea that plants _adapt_ to mechanical stress doesn't it?

As I said when I first posted to this group, my background is in
agricultural botany.  However, I spent such a long time measuring 
things with an eyepiece micrometer that I decided to investigate image
analysis as a way of reducing the amount of tedious work involved.

I'm particularly interested in differences in anatomy in relation to
factors of agricultural/economic significance (such as resistance to
lodging, or degradeability in the rumen).  But, as anyone who tries to
use it will testify, there is far more to image analysis than meets the
eye (!) if you see what I mean ...
