About the Book

Die technologischen Eigenschaften von Cedrela odorata wurden an 11 Bäumen bestimmt, die auf drei Plantagen in zwei ökologisch-floristischen Zonen in Togo gefällt wurden. Der Einfluss von waldbaulichen und biophysikalischen Faktoren wurde anhand des Kernholzanteils bestimmt, der anhand von zwei Scheiben gemessen wurde, die 1,30 m vom Stamm eines jeden Baumes entfernt entnommen wurden. Die Ergebnisse zeigen: 1) Der durchschnittliche Kernholzanteil von 36 Jahre alten Cedrela-Bäumen beträgt 88,54% und ist damit höher als der von Gmelina- und Teakbäumen aus togoischen Plantagen. 2. Der Stammdurchmesser sowie die ökologischen und bodenkundlichen Bedingungen an den Ernteorten haben einen Einfluss auf diesen Prozentsatz. 3. Bei gleichem Durchmesser weisen Bäume, die in der ökologischen Zone 4 entnommen wurden, einen signifikanten Unterschied zu Bäumen aus der ökologischen Zone 3 auf. 4. Der Gefäßdurchmesser, der sowohl in Querschnitten als auch in Tangential- und Radialschnitten gemessen wurde, unterscheidet sich signifikant zwischen den ökologischen Zonen. 5. Die Gefäßlänge unterscheidet sich nicht signifikant zwischen den Standorten. 6. PSF, 12%ige Dichte und statischer Biege-Elastizitätsmodul variieren mit dem Kambialalter.
