Conifer Vertical Righting Ability Questions
What is it that causes a conifer to grow straight up vertically at 90 degrees from the earth?
Are they strictly following the sun at midday or do they grow against gravity?
Is this tendency more pronounced in mountain specimens? IF so is this genetic or due to elevation?
If you bring mountain specimens down to lower elevations do they lose some of their ability to grow vertically due to the thicker atmosphere shielding the sun's rays?
Does the previous slant orientation of the trunk (if at an angle) override the tendency to grow up perpendicular to the earth?
If the tip of the central leader is bowed over in direction of predominant wind, how does it overcome this to grow erect vertically and perpendicular to the earth? (observed in Arizona Cypress and Eastern Red Cedar, but other conifers also seem to have similar traits).
(All this started with a Carolina Sapphire planted at an angle with the prevailing summer wind that has not righted itself compared to ERC and AC seedling which grow perpendicular to the earth).
