Relationships of growth rate and mechanical properties in sweetgum, Liquidambar styraciflua
Sweetgum, Liquidambar styraciflua, is a diffuse-porous hardwood occurring in the southeastern United States. In this observational study, trees from two plantations of sweetgum were evaluated for mechanical properties. The two plantations were similar in age, soil type, competition control, and …

Effects of Tornado Damage, Prescribed Fire, and Salvage Logging on Oak (Quercus Spp.) Saplings in Upland Oak Forests in Northern Mississippi
… such as red maple (Acer rubrum L.) and sweetgum (Liquidambar styraciflua L.). Partial thinning of trees folloby prescribed fire can regenerate oaks in managed timber stands. A severe tornado occurred on a monitored oak stand in northern Mississippi. Of the damaged plots, some were treated with …

Seasonal effects of elevated carbon dioxide, competition, and water stress on gas exchange and growth of loblolly pine and sweetgum grown in open-top chambers
Loblolly pIne (Pinus taeda) and sweetgum (Liquidambar styraciflua) were grown in miniature stands at 7.6-cm spacings outdoors in open-top chambers (4.6 m in diameter and 3.5 m tall) for 16 months. Treatments consisted of ambient- and elevated-CO₂ , drought-stressed and well-watered, and stand type …

Monomeric Ellagitannins in Oaks and Sweetgum
… of white oak (Quercus alba) and sweetgum (Liquidambar styraciflua) were investigated for their possible use as models for ellagitannin biosynthesis. It was found that oak callus tissue cultures (Quercus alba) are capable of producing ellagitannins, and the production and profile of …
