Sage (Salvia officinalis) Oils

Abstract Sage is perennial plant included in the Salvia officinalis species, which belongs to the Labiatea family. It is also known as common sage and garden sage. Medical and culinary use of this medicinal herb dates back to ancient times. The most important components of S. officinalis , which is commonly grown in many Mediterranean countries, are phenolic components. Sage has antimicrobial, antioxidant, antiviral, and immunosuppressive effects, so its medical and aromatic usage is important. In addition to this, sage is used traditionally for different purposes, such as the preservation of natural and processed food, as a sweetener, or for food coloring.

Allelopathic Effect of Sage and Turkish Oregano Volatile Oils on In Vitro in Sainfoin (Onobrychis viciifolia)

Sainfoin has little atention for plant tissue culture studies. However, genetic engineering applications of gene transfer can be done today. Therefore, first different methods are used in tissue culture (For example, using of different hormones for plant growing) and be given importance. In this study, the effect of different concentration (0-5-10-20-30 ppm) sage (Salvia officinalis L.) and Turkish oregano (Origanum onites L.) have profound effects on morphology of the tissues that grow from the initial sainfoin explant. The study was arranged in factorials with 6 replications and of variance was done using statistical analysis system (SAS) software. The data collected included the rate of seed germination, plant length, root number and root length. The highest seed germination, plant length and root length was obtained on sage volatile oil. Used both volatile oil reduced the germination ratio. Sage increased the plant and root length. Even so, Turkish orego significantly reduced plant length and is root number increased.

Plant Volatile Compounds in Growth

Plants synthesise volatile organic compounds (VOCs) in various tissues against stresses regarding herbivores, plant viruses, pathogens, temperature, humidity, light ozone, food usability, etc., and for physiologic processes such as plant development, seed formation and germination, pollination and fruit ripening. These compounds are synthesised in all parts of plants, especially flowers, fruits, roots, xylems and cells, and just as they may be effective in the tissues they are produced, they may be transferred to other parts of the plants and show their effect there.
