Crown structure of Eucalyptus globulus Labill. in a coppiced plantation
Forest biomass production is a function of photosynthetically active radiation intercepted by the foliage (Jarvis and Leverenz 1983). It has been shown that total aboveground biomass production by Eucalyptus globulus stands is linearly dependent on the solar radiation intercepted by the canopy (Linder 1985). Canopy characteristics such as leaf area index, vertical distribution of foliage, branch and leaf inclination angles, distribution of leaf azimuthal angles and grouping of foliage affect the interception of radiation and therefore forest primary productivity (Jarvis and Leverenz 1983). These canopy characteristics result from the interaction between two types of processes: 1) the genetically determined “growth plan” that may be reiterated in response to accidental damage incurred in the crown (Tomlinson 1983) and 2) environmental influences on the growth and development of branches and leaves. The objective of this work was to elaborate the crown structure of trees in a Eucalyptus globulus coppiced plantation as part of a larger study of production in these plantations.
