Question

the density of trees depends upon​

Answer 1

Explanation:

Abstract

Key message

In a tropical rainforest of Madagascar, tree species differed in average wood density depending on their light requirements and on the soil type. Tree diameter had no effect. None of these factors influenced the variation of density related to the distance to the pith.

Context

Wood density (WD) is an important wood property as it correlates with several functional tree traits and mechanical wood properties. Furthermore, wood density is often used in forest biomass and carbon stock estimates. The variation in wood density depends on a range of intrinsic or environmental factors.

Aims

This study investigated the effect of species, tree diameter, soil types and the distance from the pith on wood density in native hardwood species from a natural, mid-elevation rainforest in Madagascar.

Methods

We extracted pith-to-bark core samples from the trunk of 204 trees from 23 species. Each wood core was sectioned into 1 cm-long segments on which measures of volume and weight were performed. Within-tree and between-tree variations of wood density were analysed.
