Abstract:
In this study, the analysis of compatible soluble compounds such as content of total soluble sugar, proline and total protein as one of the adaptation mechanisms of Amygdalus haussknechtii L. under stress at three different altitude level of Qalajeh mountain in Ilam province was evaluated. The results indicated that with increasing altitude altitude, the amount of net photosynthesis decreased from ۳.۲۶ to ۱.۵۶ (μmol / m۲.s), and the transpiration varied between ۰.۸۰ to ۱.۵۰ (mmol / m۲.s). The results showed that with increasing altitude, the amount of total sugar, proline and protein compounds increased significantly (p<۵). So that the amount of soluble sugar compounds from ۴۳.۹۱ to ۵۱.۹۴ (mg / g dry weight), the amount of proline from ۳.۱۳ to ۳.۸۹ (mg / g dry weight) and total protein from ۳.۲۹ to ۴.۱۶ (mg / g dry weight) increased. There is a significant negative correlation (p<۱) between these compounds and photosynthetic parameters (net photosynthesis and transpiration), which indicated the importance of these compounds in plants under strss and as one of the most important adaptation strategies in plants.
