Compartmentation of ions and organic compounds in Salicornia brachiata Roxb.

Abstract

The actively growing stems of Salicomia brachiata (60-d old) were dissected into three major tissue layers: vascular, spongy mesophyll and palisade. Each layer was analysed for chlorophyll, protein, amino acids, and sugar contents and the activities of ATPase and phosphatase (alkaline and acid). The differences in organic compounds and enzyme activities in these different tissues have been correlated with the ion content of the corresponding tissues. © 1993 Institute of Experimental Botany.
