Effects of compression wood on hydraulic conductivity in Douglas-fir branches

Purpose

Compression wood forms on the undersides of branches to support their weight against gravity. I have found in previous hydraulic work that this compression wood conducts very little water. In this study, I plan to measure hydraulic conductivity both wit
