The Investigation on Difference of Transpiration Rate Per Unit Leaf Area Between Isolated Zelkova Tree and One Situating at the Edge of Group Trees, Using Lysimeter Method

Abstract

A test was performed for a Zelkova tree situating at the edge of group trees in a same mode as our study of isolated Zelkova to measure transpiration rate per unit leaf area under the same condition. As a result, transpiration rate of the isolated Zelkova was about 70 percent more than that of one at the edge of group trees. From this, it was investigated and confirmed that lower surrounding plant density results in higher transpiration rate of the tree.
