Changes in proline level and peroxidase activity in bean embryo and cotiledon were studied in response to salinity conditions. Activity of peroxidases (EC 1.11.1.7) in bean embryo and cotiledon (Phaseolus vulgaris L. cv. Carioca) was higher than in seedlings growing in the absence of NaCl. Proline level decresead constantly in bean embryo growing in saline conditions. However, in cotiledon the proline content increased progressively in the absence and presence of NaCl in growth solution.
