Morphological, biochemical and physiological responses of Teucrium polium L. to drought stress

Drought stress is one of the most important environmental stresses in Iran. Teucrium polium is a medicinal plant from family of lamiaceae that grows in the rocky regions of Europe and southwestern Asia, including Iran.

In order to investigate the effect of drought stress on Tulip plants, an experimental design was designed in a completely randomized design and performed in a pot with three replications. Treatments of 100, 70 and 40% of field capacity were applied, essential oil was collected by Clevenger apparatus and essential oil was analyzed and identified by GC / MS apparatus.

By analyzing the essential oil, it was found that this plant is rich in antibacterial metabolites such as beta-pinene and beta-carbophylline, which are of great importance in pharmacy. Also, the plant cultivar resists drought stress by using some drought tolerance mechanisms such as increasing root length, increasing proline and protein. Therefore, it is a very suitable medicinal plant for planting in dry and waterlogged areas of Iran.
