Title: Biological response of plantation cottonwood to spacing, pruning and thinning

Author: Gascon, R. J.; Krinard, R. M.;

Date: 1976

Source: In: Symposium on eastern cottonwood and related species. Louisiana State University, Baton Rouge, LA. 385-391.

Publication Series: Paper (invited, offered, keynote)

Description: A literature review and a sampling of data obtained from cottonwood growers of the biological response of plantation-grown cottonwood trees to initial spacings in the Midsouth have indicated the following trends: as spacing increased, dbh increased, height of dominants not practically affected, total cubic volume decreased, basal area decreased, natural pruning decreased, and, regardless of spacing, mean annual diameter growth peaked in the second or third year. Thinnings have neither increased diameter growth of residual trees nor greatly changed total cubic volume yields. Pruning should be restricted to less than 50 percent of total tree height. Mid-growing season pruning seems to produce less branching than dormant or early season pruning.

Keywords: Populus deltoides, growth, artificial regeneration, increment
