Density, humidity, and nitrogen content of dominant wood species of floodplain forests (várzea) in Amazonia (original) (raw)
Abstract
The bulk density in the wood of 15 dominant tree species of white-water floodplain forests (várzea) of Amazonia varies between 0.235 and 0.716 g/cm3 (average 0.495±0.002 g/cm3). The mean wood humidity is 115.1% dry weight (variation ≈50−260%). Nitrogen concentrations vary between 0.03 and 0.50% (average 0.20±0.002). Ecological and technical consequences of the results (implications for wood decay in this ecosystem, and potentialities for commercial use of várzea wood) are pointed out.
Zusammenfassung
Die Raumdichte im Holz von 15 in Weißwasser-Überschwemmungswäldern (várzea) des Amazonas dominanten Baumarten liegt zwischen 0,235 und 0,716 g/cm3 (Mittel 0,495±0,002 g/cm3). Die mittlere Holzfeuchte liegt bei 115,1% Trockengewicht (Variation ≈50–260%). Stickstoffkonzentrationen liegen zwischen 0,03 und 0,50% (Mittel 0,20±0,002). Ökologische und technische Konsequenzen dieser Ergebnisse (Folgerungen für den Holzabbau in diesem Ökosystem und Möglichkeiten der kommerziellen Nutzung von várzea-Holzarten) werden aufgezeigt.
