Özet

In the present study, wild orchardgrass ( Dactylis glomerata L.) collected from four different locations (Oltu, Olur, Uzundere and Ulubaǧ) of Erzurum (Turkey) were used to investigate various electrophoretic analyses within and between four ecotypes based on peroxidase (PRX), polyphenol oxidase (PPO) and malate dehydrogenase (MDH) enzymes. Four natural populations of Dactylis glomerata showed genetic variability within and among ecotypes based on similarities and polymorphism of isoenzyme bands. In addition, a dendogram analysis was made according to band patterns indicating that ecotypes could be grouped showing characteristics in relation to each other, notably Oltu-Ulubaǧ and Olur-Uzundere. However, the degree of relationship of Oltu-Ulubaǧ (6 units) was higher than Olur-Uzundere (12 units). © 2002 Taylor & Francis.
