Eastern white pine provenance tests in Illinois: twenty-year plantation performance.

Abstract

White pine [Pinus strobus] seedlots obtained from 16 stands throughout the natural range were tested in plantations established in central and southern Illinois. Growth of trees of the 16 provenances was similar at the two locations and seedlot differences have steadily diminished. Height at age 5 was a good predictor of height and diameter at age 20.
