Reaction wood

[daltontrees]

Am thinking about that....

[treeseer]

Positively it is--one kind flexes, the other does not! But again in the introduction here, Dr. T makes clear the issues with assuming any wood is 'normal'.

Down to earth with a Bump today.

 

My definition of reaction wood would be the time in seconds it takes to make a brand new saw chain blunt.

I had a go at another piece of Ash today from a big tree which had become damaged at about a foot above ground so that only a third of the circumference was supporting the whole tree.

 

My reaction was predictable after sharpening the new chain to see it blunt again

in about twenty seconds!

 

I don't know about lignin and cellulose content, more like a mixture of iron filings and flint!

If anyone is still interested in this, or wants a little light reading after the turkey, I've just come across a paper "patterns of xylem variation within a tree" by Barbara L Gartner. Lots of citations to other work in the article - so may be of interest. It's freely available online too.

You're just waiting to see who's mad, sad or bad enough to ask.....!

 

Is it a simple google job or are you offering a link??

I could probably find a link. My missus was on ebay and a book popped up by the same author. She saved it for me, thinking it was something relevant to my studies and then later searches produced another paper- which was relevant to another assignment ( and this thread)

 

I've got it if you want it:001_tt2: or you could google it:001_tt2:

 

If you can't find it. PM with your Email address and I'll send it.

 

Mad, sad or bad enough to ask.....!

I think there's some people who have a desire for knowledge and a better understanding of 'things'. Personally I do and because of the assistance I've recieved from others towards that, I just do a bit to pass it on.

[kevinjohnsonmbe]

Yes please!

 

I'll send over email address by PM, not sure which category I fit in or if it's a combo!

 

Sharing the knowledge is appreciated, subject to a decision, I'm probably just a small push from embarking on a similar route that you're well into so it is much appreciated!

Sorry I missed this, but we will be talking soon anyway.

 

As I'm always being reminded, "every day is a school day" and "it's all about the learning"

Quickly googleable, gave it a read. Very useful info for those who follow tree strength formulas that assume homogeneity. Bah humbug!
