The area of tertiary marls of watershed of Oued Mina is characterized by a semi-arid
climate with a temperature sometimes reaching the threshold of 41,2 °C between July and
January, rare and irregular torrential rains. ...
Salinity is a major abiotic stress affecting crops and plants production. Oxidative stress associated with it is often caused by excessive generation of reactive oxygen species. One of the mechanisms of non-enzymatic defense ...
Equine races in Algeria, constitute an inheritance biological, cultural and historical inestimable, that it is urgent to preserve and rehabilitate.
