Estimating Single Leaf Area of Eucalyptus (Eucalyptus grandis x Eucalyptus urophylla) Using Leaf Length and Width

Leaf area plays an important role in tree growth modeling and physiological process. There is an interest for leaf area measurement methods that are simple, quick and that will not destroy the leaf. We developed equations to estimate single leaf area (LA) by using length (L) and width (W) for Eucalyptus (Eucalyptus grandis × Eucalyptus urophylla). Totally, 426 leaves were sampled from 25 trees in south China. The model precisions are beyond 95 percent. It provides a simple and reliable method for estimating single leaf area, and has good potential to be used in a functional-structural model of Eucalyptus.
