Abstract:
Four common aromatic plants, Salvia fruticosa Miller, Coridothymus capitatus (L.) Reichenb. fil., Satureja thymbra (L.), Origanum vulgare L. ssp. hirtum (Link) letswaart have been selected for a study on the influence of environmental and genetic factors on essential oil yield of natural populations found in Crete.
Results from the first sampling (autumn) showed a great variation between populations. Salvia fruticosa showed an increase in essential oil yield from western to eastern longitudes, while in Coridothymus capitatus population growing in the Southern side were more productive than Northern, especially in Central and Eastern Crete. Satureja thymbra showed some populations with very high essential oil yield.
The lack of correlation between the results and the environmental parameters indicates genetic differences between populations. Origanum vulgare was only distributed in Western Crete and showed very low essential oil yield.
