Study of the Morphological and Physiology Variability of Anarshitan Medicinal tree (Tecomella undulate )

Anarshitan is almost evergreen tree which due to its beautiful flowers, high temperature and drought tolerance, sand fixation, treating some diseases and making wood is of great importance.  This study was conducted to evaluate the morphological and physiological characteristics of Tecomella undulate  in 7 habitats of Jiroft city in Kerman province . The results showed that most traits were significant in terms of genotype, confirming the presence of diversity in each trait. As the altitude increased, plant height, leaf length and width, fresh and dry weight and stem diameter showed a decreasing trend. The most activity of antioxidant enzymes was recorded in the leaves of Amberabad and Gomrokan areas.The correlation coefficients between the traits showed a significant positive or negative relationship between some vegetative and physiological traits. Finally, this diversity among the sample population in the southern regions of the country can be regarded as a valuable genetic source for plant breeding.
