Anaerobic Fermentation in the Tissues of Conifers

Purpose

Remove increment cores from trees for fresh inner bark and sapwood tissues which are returned to the laboratory for fermentation experiments. April and May 1991- Laboratory procedures are being developed. Anticipate the need to sample 20 trees or less,

Determinants of Sapwood

Purpose

The cores are taken and then transported back to the lab for Gas Chromatograph analysis. Through seasonal sampling and their means, we are trying to gain an understanding as to the contributions of stem respiration to the Carbon Budgets of forest ecosyst

Heartwood Development in Douglas-fir

Purpose

To monitor over the course of a year the relationship between energy reserve materials in the sapwood and phloem, and the quantity of extractives deposited in the newly formed heartwood. Three treatment groups, consisting of 10 trees each, will be create

Radial Gradients of axial flow in hardwoods

Purpose

The knowledge of how trees work has been researched for many years, but due to their complexity there are still many questions to answer. Little research has been conducted related to sapwood structures that link the radial water movement and its contrib
