DescriptionExposure to elevated levels of atmospheric CO2 for a period of 17 years resulted in small but statistically significant decreases in wood basic specific gravity and number of rays per millimeter. Other anatomical characteristics (percentages of tissues, number of vessels per square millimeter, vessel diameters, and fiber wall thickness) were unaffected by treatment. Differences due to distance from pith were important, but cardinal direction (north, south, east, west) was not.
