Seed Germination Ability and Biochemical Features of Two Teucrium Taxa (Germander) of Lamiaceae

Abstract

Teucrium chamaedrys subsp. chamaedrys and Teucrium polium, from the Lamiaceae family, have ornamental, medicinal, and aromatic usage potentials. In this study, seed germination and biochemical features of samples of two taxa grown in natural habitat and cultivated were determined. Seed germination tests were carried out in petri dishes. Phenological and biochemical characteristics were performed on the seedlings and grown in viols obtained from two different origins. While germination rate was between 41% and 46% in T. chamaedrys, it was 33% in T. polium. In T. chamaedrys the seedling raising rate was between 16% and 26%, however, it was determined as 33.3% and 26.7% in T. polium, natural and cultivated plants, respectively. In terms of macro and micro elements, no statistical difference was observed in seedlings of both origins. Germacrene-D was determined with the highest amount in T. chamaedrys as 41.1% in natural plants seedlings and 40.46% in the cultivated ones. Moreover, β-myrcene in T. polium was found to be the major component in both seedlings as 20.2% and 23.4%, respectively.
