Trait-based ecology using conduits comparison approach
This study conducted to quantify and compare the variation among root, stem, and branch wood of Acacia salicina and Albizia lebbeck. Results of this study revealed that the proportion of wood elements is quite similar. The wood cells decrease in length and width (diameter) in the acropetal direction. These traits indicate the principles of the hydraulic architecture of a tree as a perfect adaptation for maintaining the pressure gradient. A. lebbeck has the higher hydraulic conductivity and non-lumen fraction value. It indicates that A. lebbeck has a higher photosynthetic capacity and specific gravity. Thereafter, all of the vulnerability indexes are greater than 3, so both of examined species categorise as mesomorphy species. However, in arid circumstance, A. salicina is potentially much stronger to withstand drought-prone than A. lebbeck.
