The distribution of foliage density on single plants

Abstract

Means are developed for estimating the radial distribution of foliage density and of "foliage area index" from laterally observed distributions on single plants. The analysis depends on the assumption of axial symmetry.

The analysis is applied to Warren Wilson's observations on saltbush. Characteristic patterns of distribution of leaves, stems, and inflorescences are found. The estimated "foliage area index" exceeds 13 at the plant axis.
