Seed Germination and Physiology

In the study, it was aimed to determine whether the essential oil components (geraniol, carvacrol, citronellol and thymol) and their different concentrations (0, 2, 5, 10 and 20 ml/petri) would cause any allelopathic effects on the germination of wheat seeds. The experiment was carried out in the laboratory environment according to the divided plots experimental design in random plots. The effects of allelochemical species (Carvacrol, Thymol, Geraniol, Citronellol) and their doses were found to be statistically significant (p<0.01) on the germination rate and seedling dry weight of wheat seeds. The effects of allelochemical species (p<0.05) and doses (p<0.01) on seedling fresh weight were found to be statistically significant. As a result, it was determined that some of the herbal allelochemicals used were effective on seed germination and seedling growth in wheat, and the effect ratio increased as the dose increased. It is thought that some essential oil components can be used in the production of bio-herbicides for winter grass weeds, provided that similar studies are carried out on winter crop plants.
