Sažetak

A pot culture experiment was carried out in Phyllanthus amarus plants in order to study the effect of calcium chloride (CaCl2) as an agent ameliorating sodium chloride (NaCl) stress. The plants were raised in pots and salinity stress was imposed by 80 mM of NaCl. The ameliorating effect of CaCl2 was studied by giving 5mMCaCl2 to the stressed plants. NaCl-stressed plants showed decreased proteins, total sugars, polyphenol oxidase and catalase activity with increased free amino acids, proline and peroxidase activities. When CaCl2 was combined with NaCl, the CaCl2 altered overall plant metabolism and paved the way for partial amelioration of the oxidative stress caused by salinity.
