DescriptionOleoresin viscosity was measured in slash pine (Pinus elliottii var. elliottii) trees of known genetic origin over a 1-year period. A strong broad-sense heritability of this trait was found. Seasonal variation followed a definite pattern, with the highest viscosities occurring in early spring and a gradual decline occurring in late spring and summer. This decline began earlier at the 1-foot sampling level than at the 6- or 11-foot levels. Aspect from which samples were taken did not affect viscosity.
