The present research was conducted to study the resistance of Acasia tree which were
near to Banias- Jableh freeway. This study was performed by study the stomata and its
distribution on the upper and down leaf surfaces.
Also, a concentration of c
hlorophyll and a severity of photosynthesis, then compared
the results between the polluted region with the control one.
Results showed that a number of stomata decreased in polluted region compared to
the control one, where this reduction play a role in reduce the injury resulting from gas air
pollutants, and this reflexes on the severity of photosynthesis and the chlorophyll.
