The current research aims to investigate some eco-physiological factors of Ziziphora clinopodioides Lam. subsp. rigida (Bioss.) Rech. f. in different habitats. Studied parameters included topography, climate, and physiochemical properties of soil. Co-dominant plant, phenology, and vegetation variation were considered, too. In following, the effect of different climatic conditions on some physiological traits of Z. clinopodioides were investigated. For this purpose, five Z. clinopodioides populations were collected at two phenological stages (vegetative and full flowering).  The highest density (0.37) and frequency (23.33%) were registered in Deh Bala and the lowest were in Damgahan and Tezerjan. Based on standard methods pH (7.5-8.0) and EC (0.633-1.470 dc/m) were calculated and the calculated data was different in various habitats. The content of chlorophyll a (9.73–13.18 mg/g), chlorophyll b (2.02–2.88 mg/g), total chlorophyll (11.76–15.98 mg/g), carotenoid (4.48–5.95 mg/g), proline (0.360–0.371 mg/g), and soluble sugar (0.18–0.23 mg/g) varied in the studied species. The phenological stages and climatic conditions significantly affected on the studied pigments except chlorophyll b. The interaction between phenological stages and environmental conditions effected on soluble sugar significantly.
