    Description

    In an analysis of Australian grown P. radiata marked changes were found in the relative proportions and compositions of the resin acids, fatty acids, and fatty acid esters associated with heartwood formation. While the proportion of resin acids increased substantially in the heartwood, there was little change in resin acid composition from outer sapwood to inner heartwood. Extracts from wood of three large trees and samples of oleoresin from three small trees contained resin acids of similar composition.
