Description
Summary:The rapeseed is the third most important edible oil source in the world, after soybean and palm. This plant is very sensitive to salt stress throughout the growth and development cycle. Salt stress reduces plant growth and productivity and can affected several physiological and biochemical process. For this reason, this study was carried out to determine early the effects of NaCl treatment on the protein content, amylase (EC 3.2.1.1), acide phosphatase (E.C. 3.1.3.2), peroxidase (EC 1.11.1.7) and catalase (EC 1.11.1.6) in young rape plant (Brassica napus L. var Exagone). The rape seed were treated four hour with three NaCl solutions (50mM, 100mM, 150mM) comparatively with a control who wasn’t exposed at treatment. Amylase activity was inhibited by all used salts concentrations at both time intervals studied. Salinity stimulated the acid phosphatase activity, more intense at 4 days and moderately at 7 days after treatment. The activity of the two assayed antioxidant enzymes (except peroxidase in the second period) increase in salinity conditions with increasing salt concentration. Soluble protein content is reduced compared to the control at both studied intervals.
