| Abstract | ||
| Tikrit is one of the city situated in middle of Iraq, at last years, it became green and more active with ornamental shrubs ,trees at roads sides and streets medians . The study examined air pollution tolerance indices (APTI) of nine of those trees and shrubs which mentioned above and its effect on physiological and biochemical parameters; leaf relative water content (RWC) ascorbic acid content (AA), total leaf chlorophyll content (TCh) and leaf extract pH were used to compute the APTI values. The result showed that combining variety of these parameters gave a more reliable result than those of individual parameter. The result showed order of tolerance as Eucalyptus camaldulensis > Albizzia lebbek > Olea europaea > Nerium aleander >Ziziphus spina-christi > Melia azederach > Dodonaea viscosa > Biota orientalis > Callistemon laneeloata . | ||
