A Case Study in Populus canescens to Estimate the Leaf Area Index

Abstract

A 25-year old Populus canescens stand was selected for sampling to estimate the one-side leaf surface area per unit ground area. A portable area meter was used to determine leaf surface areas of a sample of branches of the first order. Different unweighted and weighted regression equations were compared to estimate leaf surface area. The estimated tree leaf areas were regressed on D.B.H., with unit weight being assigned to the single observation.
