Effect of First Generation Genetic Improvement and Vegetation Control on Growth

A designed experimental study was established at 16 locations in the Coastal Plain region of Georgia and northern Florida, and at 15 locations in the Piedmont region of South Carolina, Georgia, and Alabama. The objective of the study was to evaluate the impacts of first generation genetic improvement, and of combining genetic improvement and vegetation control on yields of loblolly pine. Two levels of competition were either none other than that provided by operational site preparation or complete control. Genetic improvement was either unimproved, bulk lot first generation improved stock or single family.
