Abstract :
Garden thyme, herbaceous perennial plant, is one of the most important medicinal plants. The treatment of seeds to reduce the time between seed sowing and seedling emergence is known as seed priming. This study was conducted to evaluate the effects of ascorbic acid (0, 300, 600, 900, 1200 µM) as priming agent on growth characteristics of garden thyme transplants in a completely randomized design with three replications. The maximum shoot height, shoot fresh weight, shoot dry weight, root fresh weight and root dry weight were obtained at concentration 900 µM of ascorbic acid.
