Abstract
The concentration of monoterpenes in
Pinus monticola Dougl. has been shown to be genetically controlled (Hanover, in preparation). Genetic control of terpene concentration has been implied, also, from analyses of parents or interspecies hybrids in other species (Bannister et al. 1959; Williams and Bannister 1962; Smith 1964, and Forde 1964). Evidence that genes regulate the formation of plant terpenes has stimulated the use of the terpenes as an aid in population studies. Bannister et al. (1962) showed significant variation in α-pinene and β-pinene between three populations of
Pinus radiata in California. Also, Forde and Blight (1964) found that
Pinus muricata Don in California could be classified into three different groups according to chemical composition. The monoterpene composition of
Pseudotsuga has not been defined adequately although Cvrkal and Janak (1959) included
Pseudotsuga douglasii Lindl. among several conifers they examined.
