Growth of salt‐sensitive Plantago media L. and salt‐tolerant P. coronopus L. and P. maritima L. was followed under saline conditions. Growth was reduced according to the ecological features of these species: P. media was sensitive to 25 m M NaCl, while P, coronopus and P. maritima could grow in 150 m M and 300 m M NaCl, respectively. The three Plantago species accumulated Na + in the shoot and maintained a relatively low Na + level in the root. K + . Mg 2+ and Ca 2+ levels of both shoots and roots decreased with increasing salinity. The results suggest that the difference between salt‐resistant and salt‐sensitive species is located in the ion secretory system which is involved in the ion translocation from the root to the shoot rather than in the primary uptake process through the plasmalemma of the cortical cells.
