Effectivity of anti-oxidative enzymatic system on diminishing the oxidative stress induced by aluminium in chickpea (Cicer arietinum L.) seedlings Braz. J. Plant Physiol.
Singh,Sushant; Verma,Anil; Dubey,Vikash Kumar.
We explore physiological and biochemical response under increasing aluminium stress at different time interval in chickpea seedlings (Cicer arietinum L.). Germination percentage and root length were found to be highly reduced under increasing metal stress. Aluminium induced oxidative stress and led to fluctuations in antioxidative activity responses. Roots showed higher antioxidative activity compared to shoots. Low concentration of aluminium after a brief treatment induced higher superoxide dismutase (SOD; EC 1.15.1.1), ascorbate peroxidase (APX; EC 1.11.1.11) and guaiacol peroxidase (GPX; EC 1.11.1.7) activity whereas longer duration of treatment led to decrease in these activities. Malondialdehyde concentration indicated higher oxidative damage in roots...
