The characterization of the hairy medic

The aim of this study was conducted to determine the morphological characteristics of the annual species Hairy (Burr) Medic (Medicago polymorpha) grown in native flora of Southeastern Anatolian region.The annual Medics, including genus medicago (Medicago L.), complete their life cycle in a year. Generally, the annuals naturally grow in the different temperature and growth seasons in Mediterranean?s countries.The vegetation observations were obtained during 50% flowering period and the generatives were during physiological period.The hairy Medic (Medicago polymorpha) collected in 24 different ecological and geographical part of Southeastern Anatolia Region were analyzed by comparing the morphological structure and diversity.The observations were observed from sixteen morphological and botanical characters. The highest plant height was determined 103 cm (Kurtalan Erdurağı-Magrip/Siirt). Number of main branches per plant ranged from 1.00 to 4.67 per plant. The weight of green herbage varied between 5.07 g (Siverek-Şanlıurfa) and 18.33 g (Siirt Kezer) per plant. The leaf weight per plant varied 0.2 g for Eğil/Diyarbakır and 1.8 g (Nemrut's Fountain/Adıyaman). The stem weight per plant ranged from 0.2 g (Silvan/Diyarbakır and Karacadağ/Alatosun village) to 1.8 g (Diyarbakır Dicle dam). The weight of highest fruit (0.058 g) was obtained from Diyarbakır Dicle dam. Coleoptil length ranged from 10.71 to 18.60 mm and the lowest value was determined from Diyarbakır Eğil.Key Words: Medicago polymorpha, Morphological Characteristics,
