Summary

Plants ofSuaeda fructicosa were grown in sand culture with various combinations of excess copper, silicon and sodium. Effects of different concentrations of NaCl on the activities of acid phosphatase and PEP-phosphatase were investigated in the above mentioned plants. Plants which were given extra copper without NaCl showed very poor growth compared with control plants given a normal nutrient whereas plants given extra NaCl alone or with copper displayed luxuriant growth.

Enzymes extracted from the plants given extra copper with normal nutrient levels showed stimulation in the activities of both the above mentioned enzymes. In plants supplied with extra sodium chloride the activity of acid phosphatase was inhibited and in that of PEP-phosphatase was stimulated. Sodium silicate in the growth medium eliminated both effects of extra sodium chloride.
