Black Walnut Provenance Performance in Kansas
Abstract:Fifteen seed sources of black walnut were planted at Manhattan, Kansas (39.2°N and 96.5°W) in 1967, the western edge of its natural range. After 22 years, height, dbh, and survival measurements revealed that local trees (Kansas) and trees from within 200 miles south of the planting site grew tallest. Height and dbh correlations were highly significant and increased when compared to successive 5-yr interval measurements. Geographic and climatic variables of seed sources did not provide a significant predictive regression model. Low survival limited the success of some sources, such as two from Indiana, in this Kansas plantation. North. J. Appl. For. 9(2):41-43.
