Response and Factors Affecting Tamarix Tolerance to Salinity and the growth of Tamarix in Iran desert

Abstract

Tamarix (scientific name: Tamarix) is a genus of the Tamarind family. Tamarind is a saltloving tree native to the arid regions of Eurasia and Africa and includes 55 species, of which about 35 species are found in the Middle East and 23 species in Iran. Tamarix is C3 plant. But there is resistant to salt. 

In this study, 8 field-grown Tamarix plants were irrigated with 3% (180 mM) salt for one month. Measurements of electrical conductivity (EC), physiological parameters such as stomatal conductance, stem length, leaf cover volume, chlorophyll content, and plant growth were performed on salt-treated and control plants. In the species Tamarix, the results showed that the physiological parameters of the plant showed that the plant species grown under sandy soil texture were more affected by salt exposure than the plant grown in loamy texture. Therefore, considering the greater tolerance of Tamarix to salt and/or water stress and the strict environmental regulations, the planting of native Tamarix species remains a preferred plant over non-native Tamarix around the deserts of Semnan province. 

Also Our results have shown that in general the number of trees planted per hectare varies from 1000 to 2500, but their number will vary greatly depending on the tree species and the type of planting.
