مراجعة لبعض مضادات الأكسدة و أدوارها الفسيولوجية في أشجار نخيل التمر Phoenix Dactylifera L.

Abstract EN

Plants are exposed to different types of biotic and abiotic stresses throughout their life cycle, abiotic stresses included salinity, drought, temperature (high or low), heavy metals, nutrient deficiencies, and ultraviolet rays.

Exposure to these stresses increases the production and accumulation of reactive oxygen species (ROS), which are highly reactive and cause damage to proteins, fats, carbohydrates and nucleic acids.

However, plants possess effective enzymatic and non-enzymatic defense mechanisms, and together they are called antioxidants.

This review reviews the most important antioxidants possessed by the date palm tree, Phoenix dactylifera L.

, which is exposed to various biological stresses, especially as it is characterized by its long life cycle.

It also reviews studies that dealt with the effect of exgenous of some antioxidants in improving the resistance of the date palm to the negative effects of abiotic stresses.
