Density fluctuation in annual rings of tropical timbers from central Amazonian inundation forests


, : Density fluctuation in annual rings of tropical timbers from central Amazonian inundation forests. Holz als Roh und Werkstoff 53(1): 63-67

X-ray densitometric investigations were carried out on 15 trees with distinct annual rings from inundation forests of Rio Negro and the Amazon River. The density fluctuations in the wood of 7 species showed distinct differences between earlywood and latewood at the annual ring boundaries. Samples of 4 species were chosen for dendroclimatological investigations. By means of a Textur-Analyse-System (TAS), time series of several density parameters were measured.
