| Abstract:
Oregano (Origanum vulgare L.) is a species of the Lamiaceae family recognised as an aromatic and medicinal plant and used widely both as a food source and in phytotherapy. It also provides an essential oil, synthesized in the glandular structures abundant on the leaf surface of the plant. The composition of the essential oils is subjected to variations of the active principles, partially due to the use of heterogeneous populations for agricultural purposes. Research studies have shown that it is possible to improve the quality of in-field cultivated plants using micropropagation techniques. For this paper a protocol for the in vitro propagation of a Origanum vulgare L. genotype was developed, followed by the histological analysis of glandular trichomes and the chemical characterization of the essential oils. The micropropagation protocol was found to be effective, allowing us to obtain a clone from a unique genotype. | |
