Survival and Growth of White Ash Families and Provenances 15 Years After Establishment in West Virginia

摘要

The survival, growth, and stem form of 45 white ash (Fraxinus americana L.) families nested within 22 provenances were evaluated 15 years after establishment in North Central West Virginia. Geographic family origins encompassed a wide area in the eastern and central United States, including locations from Maine in the North to Mississippi in the South to Nebraska in the West. Significant differences were identified among provenances for survival, stem form, total height. Latitude was a significant indicator of provenance performane with performance declining north and south of the plantation latitude.
