<p><italic>Stevia rebaudiana</italic> is a high-value crop because of its metabolites, such as steviol glycosides. However, it only produces a few seeds, resulting in low productivity.

The cuttings were treated with IAA at 0, 20, 40 and 60 mg/L by dipping them in the IAA solution for 1 minute, then planting in growth media (garden soil, organic compost and coco peat with a ratio of 2:1:1) and keeping them in the greenhouse. The survival percentage, root length and number, plant height, leaf number, total chlorophylls, and stomata length and number were assessed in the 3<sup>rd</sup> week. The application of 40 mg/L IAA resulted in a significant improvement in all parameters. However, IAA treatment also causes stomata abnormalities. This result suggested that stem cutting and IAA treatment significantly contribute to stevia propagation.</p>
