Analysis and comparison of essential oil components extracted from the heartwoods of Leyland cypress, Alaska yellow cedar, and Monterey cypress

Creator:

Liu, Xinfeng

Abstract:

The essential oil components of cedar heartwoods play an important role in the durability of these trees. Yet, the composition of these oils and identity of many of the compounds remains unknown, or incompletely know for some commercially important cedar heartwoods. The essential oil extracts of Alaska Yellow Cedar (Chamaecyparis...

Improving the durability of second growth timbers of naturally durable species

Creator:

Cabrera Orozco, Yohanna

Abstract:

While the heartwood of many wood species exhibits excellent resistance to fungal and insect attack, this resistance is sometimes diminished in second-growth material of the same species. The reasons for the reduced durability are unclear, but they may reflect a combination of both higher proportions of sapwood as well as...

Abstract:

We evaluated genes previously identified from a large scale functional genomics screen for their potential value to help enhance carbon sequestration in planted trees. We used poplar as a model tree species because of its abundant genetic variation, ease of gene transfer, and availability of large databases for genomic, anatomical,...
