Abstract
Determining total tree leaf area is necessary for describing tree carbon balance, growth efficiency, and other measures used in tree-level and stand-level physiological growth models. We examined the effects of vegetation control methods on the total leaf area of sapling-size plantation black walnut trees using allometric approaches. We found significant differences in total tree leaf area and cross-sectional stem area at breast height between trees receiving 100 percent (pre-emergent and post-emergent) weed control treatment and those receiving pre-emergent control or no control. Additionally, neither branch height nor weed control treatment factored significantly in determining branch leaf area (BLA), allowing for the use of a universal equation for calculating BLA in young black walnut plantations.
