Study of Changes in physiological and Enzymatic Metabolism of a Bryophyte “Rhytidium Rugosum” Under the Effect of a Herbicide “TREFLAN”

The biodiversity was preserved a long time, but the principal components of our environmentwere particularly modified by the addition of molecules resulting from the agricultural and industrial activities.These pollutants disturb the balance and the radiant energy flux of the ecosystem. They can poison the organizations and cause fast harmful changes in the environment. These changes can stress certain species and make them more vulnerable. In our work, we determined the disturbance caused by the addition of a xenobiotic and to try to bring one the behavior of mosses with respect to this herbicide. Our choice was made on a vegetal model in fact the moss (Rhytidium rugosum) since it is regarded biological indicator. We highlighted in addition to an increase of the chlorophyll (Chla, b, a+b), the disturbance of the macromolecules (glucids, proteins, proline) as well as a disturbance in the enzyme of detoxification (glutathione-SH: GSH).It seems that the specie Rhytidium rugosum is very sensitive to xenobiotic TREFLAN (pollutant).
