Abstract
The medium of tomato (Lycopersicon esculentum) cells adapted to grow i n the presence of 15 g 1(-1) NaCl had a higher peroxidase activity tha n the medium of an unadapted tomato cell line. When the adapted cells were cultured in a medium without NaCl, the value found for peroxidase activity was intermediate. The increase in peroxidase activity was pa rallel to an increase of lignin-like compounds in the cell walls, as w ell as to an increased content or appearance of neutral and basic pero xidase isoenzymes. Apparently, the high values of peroxidase activity in the medium of the salt-adapted cells reflect the changed mechanical properties of the cell wall which, in turn, could be related to the s alt adaptation process.
