Abstract

The purpose of this study was to establish plant ratings on the basis of transpiration efficiency. Three plant species (Albizia saman, Swietenia mahagoni, Delonix regia) were investigated for the rate of transpiration (T) and growth in dry weight (DW). Results revealed that the ranking of transpiration efficiency (T/DW) from highest to lowest was Swietenia mahagoni, Albizia saman, Delonix regia. Transpiration efficiency was suitable for use as a criterion for selection of plant species for use in design of city phytostructure. The potential distribution of the plant species was proposed, aimed at the maximum absorption of carbon dioxide and water drainage by transpiration mechanism.
