We discussed the importance of studying the trichomes award in
olive trees, leaves and its role in the resistance to these trees against
pollution resulting from the Banias refinery intake, through the
study of their density and distribution on a
superficial paper and
examine the concentration of chlorophyll in the leaves, and
comparing the results between the contaminated areas and the
control area .
Results showed that the density of the trichomes play a role in
protecting the ports of entry into force of pollutants into the plant
tissue, and its impact on the pigments of photosynthesis, and thus
the process of photosynthesis.
