Tree growth "vortex"

OK, maybe all of my wood-tec type friends out on LJ,s can help me figure this out. I’ve allways been fascinated with the dynamics of curing and drying wood after the harvesting process. One to overcome is of cource the growth vortex that occures in some species and not in others. One question I have is this, Is there a right-hand vortex that occures above the equator as opposed to a left hand one bellow the equator? When a tree wiggles and struggles up out of the grownd, It also “twists” to follow and face the path of the sun. But when the sun sets in the evening, does the tree pause there/sleep/and resume the same pattern in the morning? Does the tree turn back and face the sun again causing in some species a straighter grain configuration? Does the moon have a similar or modified affect? This “vortex” is what causes the directional twist in wood as it dries, so have you log home builders noticed the gentle retracting affect on 4-sided structure as it cures and dries, or is it just me? after all, it stands to reason that if all the logs are supplied from a single geografic location and all have the same vortex then thay would all conspire to roll in the same direction, either clockwize or counter clockwize, thus having a rotating affect on the stucture. Also does anyone know if there are documented studies in print about this subject?

I sujest that you get into a online L A phone book and look for the vortex mistic new age section or call tom cruz and ask him about it. phil

This sounds like heliotropism. It occurs in flowers and leaves but I never heard of trees having this trait.
It is basically the motion of plant parts in response to the suns travel. The flowers face in random directions
at night and turn back eastwards at sunrise. The flowers move by stimulating motor cells in the pulvinus
with potassium ions.

Don’t know if this is any help or just adding to the confusion but there you go anyway.

Most of the woody plants experience bending and twisting during their life before harvest.
Major influences are prevaling winds and location. The critical time of influence is during the “growing” season.
In central N. America, the winds “usually” move CCW. South winds in a NE direction, North winds in a SE direction. Hardwoods harvested from more open, less crowded conditions, exhibit the vortex more so than the softwoods harvested from denser forests. Bending during growth usually yields straighter, more flexible wood. Conversley, twisting during growth yields tougher more ridged material.
