Summary

Growth of the annualSalicornia bigelovii Torr. was found to be optimum at about 1 per cent NaCl or somewhat less than is usually reported forSalicornia herbacea L. Extremely poor survival occurs with NaCl concentrations below 0.5 per cent. Growth inhibition at NaCl concentrations above optimum seem to be more severe for root growth than for shoot growth. No effect of NaCl on succulence inS. bigelovii was detected. Transpiration on a fresh weight basis is significantly reduced at NaCl concentrations above that for optimum growth. Possible sites of NaCl action on conductivity to water are discussed.
