Cytoplasmic concentrations, fluxes of K + , Na + and Cl and microsomal membrane lipids were investigated in a salt‐sensitive and salt‐resistant variety of Zea mays. The salt resistance of Protador relative to LG H (salt‐sensitive) appears to be related to higher K + fluxes and cytoplasmic concentrations, and lower Na + and Cl fluxes and cytoplasmic concentrations, when grown in NaCl. There were no apparent differences in the simple chemical composition of root microsomal membrane lipids between the two varicties, neither were these affected by salt.
