Developing A Sampling Method To Determine Effects Of Insects On Yields In Southern Pine Seed Orchards
Describes objectives and current activities of a Seed Orchard Sampling Committee. Cooperating members of the committee are conducting sampling studies on five pine species in seven southern states. Duration of the studies is three years and results will be used to estimate impact of various destructive agents on orchard seed yields. Life tables for the pine cones of each pine species will be constructed for use in developing seed yield prediction models. Current partial results of the studies are presented.
