Leaf physiology and morphology of Castanea dentata (Marsh) Borkh., Castanea mollissima Blume, and three backcross breeding generations planted in the southern Appalachians, USA

Backcross breeding programs have been used to transfer disease resistance and other traits from one forest tree species to another in order to meet restoration objectives. Evaluating the field performance of such material is critical for determining the success of breeding programs. In eastern North America, The American Chestnut Foundation has a backcross breeding...

Wetting behaviors of phenol- and urea-formaldehyde resins as compatiblizers

Understanding wetting behavior and surface coverage of resins on a wood surface is important to obtain satisfactory adhesion and optimize adhesive application for wood composite manufacturing. Sessile and micro-droplets of urea- and phenol-formaldehyde (UF and PF) resins were generated on wood surfaces to observe wetting behaviors using three directional image...

Characterization of microwave liquefied bamboo residue and its potential use in the generation of nanofibrillated cellulosic fiber

Bamboo raw feedstocks with large particle size (20?80 mesh) were subjected to a microwave liquefaction system, and the liquefied products were separated into biopolyols and liquefied residues. Biopolyols were first analyzed by gas chromatography mass spectrometry (GC?MS), and the main components were sugar derivatives with 2?4 hydroxyl groups and phenolic compounds...

Extraction and characterization of seed oil from naturally-grown Chinese tallow trees

Seeds were collected from locally and naturally grown Chinese tallow trees (CTT) and characterized for general physical and chemical properties and fatty acid composition of the lipids. The effects of four different solvents (petroleum ether, hexane, diethyl ether, and 95 % ethanol) and two extraction methods (supercritical carbon dioxide (SC-CO2) and conventional...

Effects of climate change on ecological disturbances [Chapter 8]

This chapter describes disturbance regimes in the Intermountain Adaptation Partnership (IAP) region, and potential shifts in these regimes as a consequence of observed and projected climate change. The term "disturbance regime" describes the general temporal and spatial characteristics of a disturbance agent (e.g., insects, disease, fire, weather, human...

Mechanical and physical properties of composite panels manufactured from Chinese tallow tree furnish

Chinese tallow tree is a noxious, invasive plant in the southeastern United States. It is generally considered a nuisance and has no current commercial use. The objective of this research was to determine the technical feasibility of using the stem wood of this species for particleboard, fiberboard, and structural flakeboard. Due to its rapid growth, Chinese tallow...

First report of two cone and seed insects on Pinus flexilis

Limber pine (Pinus flexilis James) ranges in latitude from 33°N to 51°N and in elevation from 870 m above sea level (asl) in North Dakota to ~3400 m asl in Colorado (Burns and Honkala 1990). In the central Rocky Mountains, limber pine co-occurs with many tree species due to its broad elevational range (Peet 1981). Limber pine seeds are large, generally...
