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.
A morphological , anatomical and chemical study was carried out on Salvia viridis
L. (Lamiaceae) . The results showed presence of two types of trichomes :
- Glandular hairs with four or eight celled globular heads or with oval heads .
- Eglandular
hairs which are unicellular or multicellular , in addition to presence of
candle shaped eglandular hairs .
The palynological study revealed that the pollen grains were prolate and they had six
germination lines , exine appeared reticulate .
The extraction of volatile oils have been done by dry evaporation using GC/MS
technique , chromatographic analysis of these extracts have showed the presence of
complex of carboxylic acids , hydrocarbons , terpenes , esters and aldehydes .
