Résumé
Crown leaf area’ of mountain big sagebrush3 Artemisia tridentata subsp • .vaseyana _(Rydb „) s can be reliably measured by dividing crown leaf volume by mean leaf thickness* The largest, contribution to the variability of leaf area is from bush-to-bush differences* The best model of the relation between crown leaf area and bush Is ln(Y) = a + b.ln(X) where Y is croxm leaf area and X is crown leaf weight. This model fits the data better than the transform., ’ b Y = aX , . r. because the variance of croxm leaf area is proportional to bush size. Croxm leaf area varies directly with bush weight3 bush volume, stem weight, and stem volume, However, croxm leaf area varies as a power function of the linear dimensions of the croxm, area of the croxm ellipse, and surface area of the croxm.
