In the study, the plant height (cm), fresh weight (kg/da), dry weight (kg/da), dry leaf weight (kg/da), essential oil content (%), essential oil yield (1/da), artemisinin content (%), and artemisinin yield (kg/da) of ecotypes were investigated. The results of this study showed that the highest essential oil content and the highest essential oil yield were found in the Samankaya ecotype when planted at 15 plants/m2. However, the highest artemisinin content and highest artemisinin yield were found in the Serinyol ecotype when planted at 15 plants/m2. © 2002 by The Haworth Press, Inc.
