The Effect of Hormone Treatments on Germination and Seedling Characters of Sage (Salvia officinalis L.) Seeds

Abstract

Medicinal Sage is consumed as tea in sore throat and kidney diseases caused by cold and flu. It also has sedative, diuretic, antiperspirant and disinfectant effects. Thujone, which is found in the essential oil of Salvia officinalis species, is an essential oil component with very strong antiseptic and antibiotic effects. Sage (Salvia officinalis), which is a medicinal and an aromatic plant and has a wide area of usage, is cultivated due to these properties. However, the most critical cost item in the production of sage is the weeding done in the first years. The understory weeding done without using herbicides continues until the sage seedlings shield the soil and prevent the development of other herbs. The aim of this research was to determine the effects of hormone treatment on germination success and seedling morphological characters in sage seeds. Within the scope of this research, sage seeds were planted by being exposed to IAA, IBA, GA3 and NAA hormones at 1000, 2500 and 5000 ppm concentrations for 3 to 5 seconds and at 50, 100 and 200 ppm doses for 24 hours, and thus 26 applications were performed together with the control groups. The seeds were planted in sterile peat medium after the hormone treatments, and the effect of hormone treatments on the germination percentage and some seedling characters was tried to be found after 30 days of germination. As a result of the research, it was found that the hormone treatments positively affected most of seedling characters.
