ABSTRACT

A comparative study of Dactylis glomerata coastal populations from Nazaré and Figueira da Foz (Portugal) and Cabo Vilán (Galicia, NW Spain) was carried out, looking for morphologic and metabolic differences useful for distinguishing between varieties or ecotypes. The only biometric character that shows clear significant differences between populations is the ligule length of the flag leaf. The epidermis characteristics show some heterogeneity between populations. Between population variations in the amount of total lipids and of some free fatty acids were detected.


Keywords: Dactylis glomerata L., fatty acids, biometrics, epidermic papilla.
