摘要

This paper presents the work conducted on the chemical constituents of some common and widely distributed halophyte taxa from Cyprus with the aim that these studies will help in the evaluation of halophytes for different economical purposes.The plant species of Crithmum maritimum L.,Limbarda crithmoides(L.)Dumort,Atriplex portulacoides L.,Salsola kali L.,Atriplex halimus L.,Limonium oleifolium Mill.,L.meyeri(Boiss.)Kuntze;and Tetraena alba(L.f.)Beier&Thulin were collected in the middle of July.The shoot tissue and leaf samples were collected from the natural habitats and left for drying under air circulation followed by placing them in oven at 60℃ for 96 hours.The material was crushed using mortar and pestle and subjected to an analysis of macro-and micro-nutrients and biochemical compounds.K+/Na+in the leaf tissues of the dicot species showed relatively high values depicting their behavior as Na+includes but very low Cl-levels were recorded.Out of the species investigated here in 4 TFAA content was rather high.Values ranging from 0.5%to 1%dry weight were exhibited in one species.However,only 3 species showed very low TFAA values.Later may be due to low nitrogen availability in their environment.The phenetic analyses of eight halophyte species performed on the data matrix using Ntsys-pc program version 2.1 revealed that,cluster analysis of the overall results obtained here leads to 2 clusters.This discrimination appears to be as a result of their different abilities to accumulate either proline or glycine betaine.
