Application of Floristic Marker in Eco-phytosociology Method for Diagnosing Existing Intra-specific Diversity in Plants: A Case Study of Astragalus glaucops

Study was carried out on 11 disperse populations of Astragalus glaucops in Alvand mountain. Floristic-ecologic data were collected using the unit of study as mean endogenous milieou by eco-phytosociologic method. Then data obtained from five different groups of releves for this species was analyzed by Anaphyto software with FCA method. Also the study on flavonoids of populations was carried out by thin layer choromatography. obtained data were analyzed by MVSP software with Ward methods. Five groups resulted from floristic-ecologic study confirmed by flavonoid patterns. Results of floristic analyses showed five distinctive different groups of A. glaucops in the study region. Photochemical studies revealed five chemotypes, which confirmed the results of floristic studies. Between studied ecological factors, elevation was the most important ecological factor in creation intraspecific diversity. © 2010 Friends Science Publishers
