Above- and below-ground relationships in teak stands

ABSTRACT There is little information available about leaves and root of teak in Brazil. The goals of this work were to evaluate if the above-ground components, biomass and leaf area, are good biomass and root surface estimators in teak (Tectona grandis) stands. In the sampling, executed in 17 and 90-month-old teak trees established in commercial stands, the roots, stem, branches and leaves were separated to determine the dry biomass and SLA (specific leaf area) and SRA (specific root area). The leaf surface of a young tree is four times larger than the surface of an adult teak tree leaf. The fine roots surface (
