Title: Process for increasing oleoresin synthesis in pinus species

Abstract: Stimulation of oleoresin production associated with living cells can be chemically induced with dilute systemic application of ethylene or ethylene-releasing compounds. One such ethylene-releasing compound is 2-chloroethylphosphonic acid. A further increase in oleoresin production can be accomplished by using ethylene-releasing chemicals in combination with the bipyridilium salts, diquat or paraquat. Through the application of ethylene-releasing chemicals in combination with a bipyridilium salt, the effect of lightwood inducing chemicals is expanded over a larger portion of the treated tree, and more oleoresin is produced. Oleoresins are extracted from the trees by known methods, and the naval stores products are recovered therefrom.
