Early genetic selection for wood stiffness in juvenile Douglas-fir and western hemlock

Creator:

Urhan, Oguz S.

Abstract:

Wood modulus of elasticity (MOE), also known as wood stiffness, is one of the most important wood properties. Wood stiffness is a measure of the resistance to deflection, and is important because some products such as laminated veneer lumber, plywood, and dimension lumber require stiff and strong wood. Incorporating wood...

Estimating spatial changes in acoustic velocity in felled Douglas-fir stems

Creator:

Dowding, Bodie

Abstract:

To compete with other building materials, the wood products industry must find a way to increase value and lower costs. Wood stiffness is important for most wood uses. Value can be increased and costs can be lowered by sorting logs for stiffness in the woods using acoustic devices mounted on...

Impacts of Swiss needle cast on Douglas-fir tree-ring stable isotopes and tree carbohydrate reserves

Creator:

Saffell, Brandy J.

Abstract:

Understanding the mechanisms of disease in forest pathology is a critical component to learning how to most efficiently manage tree diseases like Swiss needle cast (SNC). SNC is an economically important, fungal disease of Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) that is prevalent in coastal areas of the Pacific Northwest. This...
