A Note on Prediction of Wood Properties in Yellow-Poplar

H. A. Core, W. W. Moschler, C Chang

Abstract


Increment core samples were taken from fifteen yellow-poplar trees at breast height and determinations of specific gravity and fiber length were made on selected individual growth rings. Juvenile wood and mature wood of different growth rates were compared. The results show mature wood specific gravity uncorrelated with growth rate and mature wood fiber length increasing with increasing growth rate. The extremely low correlation obtained between juvenile wood and mature wood properties within the same tree indicates that no predictive relationship exists for use in selection at a very early age.
