Key Word Index - Pinus resinosa; Pinus nigra; Pinaceae; needles; labdane diterpenes; hybrids. - The principal resin acids in the needles of Pinus resinosa are the labdane diterpenes, the new 8,13-epoxy-14-labden-19-oic acid (epimanoyl oxide acid), 8,13β-epoxy-14-labden-19-oic acid (manoyl oxide acid), 8(17),E-12,14-labdatrien-19-oic acid (communic acid) and 15-oxo-8(17)-labden-19-oic acid (imbricataloic acid).A survey of needles from representative populations of P. resinosa showed a limited variability in resin acid composition consistent with the uniformityof other traits.The composition of needle resin acids for putative P. nigra x resinosa hybrids strongly suggests the improbability of P. resinosa as the pollen parent.
