Some Factors Influencing Resin Concentration in Loblolly and Slash Pines
The resin content of the sap-wood of second-growth loblolly and slash pine trees is not constant, but varies as the minimum temperature when below 40[degree] F. Likewise, the moisture content is not constant, but varies inversely as the resin content. Over a period of time, the average resin content of both species was found to be approximately three per cent, and the average moisture content, forty-one per cent. Taking into consideration vertical position in the stem, the average resin content was found to increase from the base to the crown. Lack of resin flow for naval stores in cold weather is attributed primarily to a decrease in resin production and concentration within the tree, rather than to increased viscosity.
