Abstract

In a pot culture experiment, the effect of calcium chloride (CaCl 2) as an ameliorating agent on sodium chloride (NaCl) stress was studied in Dioscorea rotundata plants. Plants were raised in pots and exposed to salinity stress (80 mM NaCl) with or without 5 mM CaCl2. NaCl-stressed plants showed decreased protein and total sugars, and increased free amino acid and proline content. When NaCl treatment was combined with CaCl2, over-all plant metabolism was altered, with increased antioxidant enzyme activity, paving the way for partial amelioration of oxidative stress caused by salinity.
