Resumen

GAYOSO A, JORGE  y  GUERRA C, JAVIER. Carbon content in the above-ground biomass of evergreen forest in Chile. Bosque (Valdivia) [online]. 2005, vol.26, n.2, pp.33-38. ISSN 0717-9200.  http://dx.doi.org/10.4067/S0717-92002005000200005.

Carbon (C) content in stem, branches, leaves and bark from 16 tree species of the native forest in Chile was determined. The mean contents of organic C by species varied between 34.9% and 48.3% and the single mean was 43,7±0.16%. The total C content was 5,5±0.76% higher than the organic C content. Significant differences between groups of species and tree tissues were found. For all the species the stem’s C contents (44,4±0.16%) were slightly higher than those in woody branches, leaves and bark (43,5±0.21%). The highest C content was for Saxegothaea conspicua with 47,8±0.38% and the lowest for Weinmannia trichosperma, 42,6±0.54%. Through analysis of variance, the study didn’t show significant differences between deciduous species and evergreen species and forest type as it did for native coniferous and broadleaf.

Palabras clave : carbon contents; above-ground biomass; temperate rainforests.
