Microbial ecology of freshly sawn yellow-poplar lumber ( Liriodendron tulipifera L.) in two seasons
… ecology of green lumber of yellow-poplar (Liriodendron tulipifera L.) during storage as a precursor to the development of biological control agents for use on freshly sawn lumber. (Abstract shortened by UMI.).

Factors influencing basal area growth of yellow-poplar ( Liriodendron tulipifera L.) in central West Virginia
… to evaluate basal area growth of yellow-poplar (Liriodendron tulipifera L.) as related to four topographic factors (aspect, slope position, steepness, and landform), two competition variables (basal area per acre and trees per acre) and four tree characteristics (age, diameter, total height, and …

Assessment of Genetic Variation of Acer rubrum L. and Liriodendron tulipifera L. Populations in Unmanaged Forests of the Southeast United States
Acer rubrum L. and Liriodendron tulipifera L. are prolific throughout their ranges in the Southeastern U.S. and also have increasingly important roles in forestry and wood products in this region. The relatively low density and intermediate strength of the wood makes them versatile for use in many …

Effect of Minimum Suppression and Maximum Release Years on Compression Parallel to Grain Strength and Specific Gravity for Small-sized Yellow-poplar (Liriodendron tulipifera L.) Specimens
… and ring width or growth rate in yellow-poplar (Liriodendron tulipifera L.). Because most mechanical properties of wood are also closely related to specific gravity, it would thus be of interest to learn how minimum suppression and maximum release years' evidence that can be extracted from radial …

Compatible taper and volume equations for yellow-poplar in West Virginia
Yellow-poplar (Liriodendron tulipifera L.) is an important source of raw material for the forest products industry in West Virginia. Accurate taper and volume functions are an important component of most inventory systems for use in estimating upper stem diameter, form, and tree volume. Compatible …

Successive Land Surveys as Indicators of Vegetation Change in an Agricultural Landscape
… locust (Robinia pseudoacacia L.), yellow poplar (Liriodendron tulipifera L.), and scarlet oak (Quercus coccinea Muenchh.). The central change was a steady decline in white oak, probably due to the absence of fire and changes in soil properties. Chestnut replaced white oak as the dominant species, …

Coordination of physiological and morphological acclimation of shade-grown tree saplings to late-season canopy gap formation
… maple (Acer saccharum Marsh.), tulip poplar (Liriodendron tulipifera L.), and white ash (Fraxinus americana L.). Physiological acclimation responses included higher photosynthetic rates in shade-developed foliage upon exposure to higher irradiance and temperature conditions within the gap for …

An analysis of the potential effects of air pollutants emitted during coal combustion on yellow poplar and loblolly pine and influences on mycorrhizal associations of loblolly pine
Yellow poplar (Liriodendron tulipifera L.) and loblolly pine (Pinus taeda L.), families 2-8 and 540, seedlings were fumigated with 0.07 ppm ozone, 0.06 ppm sulfur dioxide 0.07 ppm ozone + 0.06 ppm sulfur dioxide, 0.06 ppm sulfur dioxide + 0.10 ppm nitrogen dioxide and 0.07 ppm ozone + 0.06 ppm …

Development of dimension lumber grade and yield estimates for yellow-poplar sawlogs and trees
… eastern hardwoods in general, and yellow-poplar (Liriodendron tulipifera L.) in particular, are underutilized. At present, dimension lumber used in light frame construction is almost exclusively manufactured from softwood species. Recent literature, research, and conferences have pointed to the …

Phenology, impact, and rearing of Lycorma delicatula (White) (Spotted Lanternfly) in Virginia
… Juglans nigra L. (Fagales: Juglandaceae), and Liriodendron tulipifera L. (Magnoliales: Magnoliaceae). Two sites in Pennsylvania that have experienced high populations and heavy feeding pressure from L. delicatula since 2016 were used to collect tree cores for analysis. I found evidence …
