Abstract

This study investigated the changes of proline, soluble sugar, Na, K and N in Atriplex lentiformis, Halostachys belangeriana and Tamarix rammossma over two seasons (winter and summer) in the field conditions. Five plants all in the same sizes and forms from each species in Chahafzal area of Yazd province were collected and the above mentioned indices were measured. Results showed that the highest amount of proline and sugar were found in Halostachys belangeriana and Atriplex lentiformis, respectively. Meanwhile, the amount of proline in all plant over summer was significantly more than winter. The amount of proline in summer in Halostchys belengeriana was also equal to 3.2 mg/gfw. In Atriplex lentiformis and Tamarix rammossma, the amount of sugar in summer was significantly more than winter. The highest amount of sugar was found in Atriplex in summer measurement which was equal to 6.8 mg/gdw. In contrast to two mentioned species, sugar content of Halostchys belengeriana in winter was more than summer. The amount of N and K were not significant in any of the species. Na in Halostchys belengeriana was significantly high compared with two other species. It is concluded that these halophyte species tolerate with different mechanisms to cope with salinity and drought stresses.
