Correlation between Wood Characteristics and Growth Characters of Pinus yunnanensis
Yong Ma · Yunnan Forestry Science and Technology · 2002
The correlation between wood characteristics and growth characters of Pinus yunnanensis were studied at the level of provenance and individual. The results of three aspects were obtained. (1) Wood grain was negatively correlated with tree height growth highly significant, and was negatively correlated with timber mechanical properties significant. (2) Timber mechanical properties were positively correlated with tree height and DBH highly significant or significant ,and was positively correlated with wood density (3) Wood density was positively correlated with tensile strength and elastic modulus highly significant; there is no obvious correlation between wood density and growth characters. From 82 individuals of 28 provenances at Yongping site and 22 individuals of 8 provenances at Damashan Kunming site, eight superior individuals were selected out by comprehensive appraisal, which provided the materials for P. yunnanensis superior individual selection of wood base panel production.
