Title: Differences in some chemical properties of innerwood and outerwood from five silviculturally different loblolly pine stands

Publication Series: Miscellaneous Publication

Description: The influence of five different silviculrural management strategies on the chemical composition (extractives, Klason lignin, holocellulose, and alpha-cellulose) of loblolly pine outerwood and innerwood was investigated. Stands that were managed in a plantation setting using growth-accelerating treatments showed higher extractive contents than the other stands. Wood from the juvenile area (innerwood) yielded more extractives than outerwood (mature wood). Holocellulose and alpha-cellulose were not significantly affected by silvicultural practice but were found in a much grearer concentration in outerwood than innerwood due to the greater density in the outerwood region. Klason lignin was inversely related to holocellulose.

Keywords: Alpha-cellulose, hot-water extractives, alcohol-benzene extractives, ether extractives, Klason lignin, holocellulose, silvicultural treatments, wood type
