Abstract
[EN] Enzymatic activity and soluble protein content in relation to salt stress tolerance were investigated in
Calendula officinalis seedlings after 24 days of treatment with different salt treatments, including
NaCl, CaCl2, MgCl2 and mixtures of them. The marigold seedlings were used in order to investigate
the possible salt-inducible responses and the possible alleviative role of calcium and magnesium salts
in respect with adverse salinity conditions. Activity of superoxide dismutase (SOD; EC 1.15.1.1) and
peroxidase (POD; EC 1.11.1.7) generally slightly decreased under salt treatments, with minor
variations from the value recorded for control series and within applied treatments. Catalase (CAT; EC
1.11.1.6) activity was stimulated by NaCl salinity and MgCl2 addition; its activity was found to be
lowest under calcium and magnesium chloride treatments solelyOprica, L.; Vicente Meana, Ó.; Boscaiu Neagu, MT.; Grigore, MN. (2016).
