Changes induced by NaCl in the sizes of both cells and vacuolar compartments of tomato seedling roots were determined using morphometric and stereological analysis. Parameters evaluated showed that cellular volume was smaller in roots grown under saline conditions than in control roots. This reduction was greater when NaCl concentration was increased. Similar behaviour can be observed in the vacuolar compartment where high concentrations of NaCl produce a reduction in vacuolar volume although the number of vacuoles per cell does not change under saline conditions.
