Those of you who are concerned about the reported damage that the
Resistograph causes when it breaches reaction zones (RZ) (Arboricultural
Journal, Vol127, No 1, pp 59 - 77), might want to consider the following:


......................Any of you that are familiar with Rayner and Boddy's
work, tree defence mechanisms to wounding in general, and the complexities
of microbial colonisation when wood is rendered dysfunctional, will be very
aware of the important limitations of this research and the caution that
should be applied when interrupting it.

David sorry to appear pedantic but did you intend to write interpreting rather
than interrupting as the words offer very different meanings and I can't
believe that anyone would knowingly wish to interrupt research even in this
context?


I find your comments extremely informative however I can't help remembering
that Schwarze's primary concern related to the size of the bore, in that RG
bores were more likely to favour colonisation through the RZ than larger
bores. Whether or not research substantiates this, at the time I saw some
sense in the thinking, probably supported by my aversion to anything invasive,
but for now I would prefer to keep an open mind.


To be fair to Schwarze, the use of sterilized samples is the only way to
obtain laboratory conditions in order to provide anything conclusive,
unfortunately one could reasonably conclude that it is only under those
conditions as opposed to field conditions that the conclusions have any
relevance. But you must start somewhere in the knowledge that any field trials
which encompass the multiple variables that would otherwise corrupt a lab
test,  would therefore provide data from which one could only extrapolate. If
I were a scientist that would appear as attractive as hugging a Monkey Puzzle.


Anyway, in an ideal world we wouldn't bore at all so I'll just close now !!
