The present study was carried out to study the proline, glycine betaine (GB) contents and lipoxygenase (LOX) activity under NaCl salinity and its amelioration by CaCl₂ during early seedling growth of groundnut (Arachis hypogaea L.). Proline and glycine betaine contents were found to be increased more by addition of CaCl₂ to the NaCl stressed seedlings than NaCl alone. NaCl treatment caused decrease in the level of LOX activity when compared to the seedlings treated with either CaCl₂ or its combination with NaCl. LOX showed a single peak with an UV absorption maximum at 235 nm on HPLC.
