cheers hama its realy good information to learn ,is the wood on the side with the larger growth rings from the tree growing at a lean been tension wood would this be more likely to rot than the tighter growth rings on the compression side

 

Your getting all the right stuff going on.

 

it depends on the fungi, some like kretzchmaria want cellulose only and prefer the tension sides for that reason, this is also proven by the modes of failure where a large stonelike fracture is laid next to a massive shear (on the compression side where little degradation occures due to high lignin contents)

 

i hope thats not too hard?

 

the thicker rings will be in angiospermous trees on the tension side, and on gymnospermous on the compresive side.

 

even vertical trees with NO lean or obvious wieght or lop sided ness, will have temnsion and compression sides, due to prevailing winds etc, torsional growth via side winds complicates this though!:sneaky2:

The Sycamore was only a tidler but was massively one sided with it leaning towards the sunlight. The crown was doing the same. It lost its original crown to squirrel damage, rot and wind throw and it sent all of its nutrients to its lower branches. It was on the verge of falling but it was marked up for removal anyway.

no matter of size, small or large, the forces of nature are all relative, and the language is always the same.:001_cool:

Yarp. If there is a little hole rot can get in and play allsorts of havoc. Bit like us i guess. If you have a little cut or a big wound and leave it to the air nasties will get in there and cause infection. Which would lead to problems in the long term.

only if the "nasties" are true nasties AND our imune system is in poor vitality due to stress (big tax bill) etc or for the tree, drought, iether way, tax or drought still leaves you felling debhilitated and dry!:lol:

Yep. The nasties may be doin you a favour but then again they might be trying to screw you over. Taking more than they actually need but still take it. Anything is suseptible it just needs the right conditions to floruish and take full effect.
