Abstract

Results at age 15 yr are presented for trees of 13 USA and 3 Canadian provenances grown in a plantation in W. central Illinois. No significant correlations were found between wood density and lat./long. or tree vol. If 2 USA provenances were excluded, d.b.h. explained 42% of the variation in wood density.
