Notes: Variation and Inheritance of Monoterpene Composition in Longleaf Pine
Abstract:Studies of phenotypic variation in monoterpene composition of longleaf pine indicated that α- and -pinene were the major components. Samples from three geographic regions indicated no regional differences, but large differences were found among individual trees and among basal stem-xylem, cortical, and needle oleoresins. Genetic analysis of cortical monoterpene composition, based on results of a 13-tree half-diallel mating design, showed that over half of the total genetic variance and slightly less than half of the phenotypic variance was of the additive genetic type.
