Geographic variation in the Rosemount, Minnesota NC-99 eastern cottonwood provenance test-- a final report

In this cottonwood provenance test, mortality between the 6th and 17th year in the field was high in many sources originating between 38 and 42 degrees north. Seventeenth year survival exceeded 75 percent only in the Minnesota and northern Ohio sources, and growth differences among origins were non-significant. The results suggest that local populations may be the most appropriate source of breeding materials for use under Minnesota condition. Additional Keywords: Provenance effects, mortality, height growth, diameter growth, diameter-height ratio, Populus deltoides.
