Provenance Variation of Wood Density in Grand Fir grandis Lindley): An Indirect. Assessment Using the Pilodyn
Abstract
Assessment of wood density using indirect method with the pilodyn was carried out on 33 provenances of grand for (Abiep grandis) grown at two Sites-Wark and Drummond Hill in Britain. Initial evaluation to deter-mine the need for multiple readings on individual trees produced repeatability value of 0.74 suggesting that a single measurement will suffice. A two-way nested ANOVA model on provenance variation indicated highly significant differences between provenances and sites. The site with a high potential for growth, Drummond Hill, produced wood of relatively lower density than Wark. This suggested that site characteristics may be a limitation on the production of high-density wood in grand fir. However, the provenances 12002 and 12042 have comparatively higher wood density irrespective of the site on which they are grown.
