The esparto (Lygeum spartum L.) is a perennial poaceae which is of significant ecological interest in the fight against the advance of the desert and desertification because of developed root system and a salinity-tolerant species. The present study aimed at to study some parameters of biological adaptation to salinity in Lygeum spartum Land to observe the effect of salinity by adding increasing concentrations of NaCl (0, 50, 100 mM). The results obtained show the negative effect of NaCl on the growth and development of the plant, salt stress led to a decrease in the growth of the plant, decrease in the concentration of flavonoids and antioxidant activity which indicate increase in the rate of inhibition of 2, 2-diphenyl-1 -picrylhydrazyl (DPPH) and an increase in the rate of malondialdehyde (MDA). These results confirm that esparto is a model plant that has an adaptive and salinity-tolerant capacity.
