Effect of Alkali-salt Stress on Anti-oxidative Enzymes of Asparagus Officinalis

Asparagus officinalis was respectively treated by NaCl,NaCO_3,complex salt(which was that NaCl,NaCO_3,NaHCO_3and NaSO_4 mixed together with equal quality.) under 0.1 mol/L,0.2 mol/L,0.3 mol/L three different concentrations.This paper mainly measured degree of damage and activities of anti-oxidative enzymes of asparagus officinalis.The results showed that neutral salt did not hurt seriously asparagus officinalis,but alkaline salt obviously damaged membranous system of asparagus officinalis,effect of complex salt stress on asparagus officinalis was between neutral salt and alkaline salt stress.Activities of POD,CAT had the same changed regulation as degree of stress,but activity of SOD did not increased significantly with increasing degree of stress.
