The purpose of this study was, to determine the effects of different treatments on bulblet formation with scale propagation in 'Madonna lily' (Lilium candidum). The research was conducted in growth chamber at Eanakkale Onsekiz Mart University, Faculty of Agriculture, Department of Horticulture in 2015-2016. Scales of Lilium candidum bulbs with 22-24 cm circumference, were used as a plant material. Effects of different incubation periods (10,12,14 weeks), incubation temperatures (10-15 degrees C, 20-25 degrees C), auxin (IBA 100 ppm, IBA 200 ppm) doses and scale positions (outer, middle, inner, center) on bulblet formation were investigated. The experiment was established according to randomised plot design with 3 replications. Some parameters like, bulblet formation ratio, bulblet number per scale, weight, diameter and height of bulblet, scale number, root number and root length of bulblet were also determined. As a conclusion, treatments have not any significant effect on bulblet formation ratio, but there were significant differences between the other parameters for some of treatments. In spite of this, incubation period of 14 weeks gives the highest average value for bulblet number per scale (1.467 piece) and bulblet height (19.105 mm). Also, the highest average value of bulblet weight (0.792 g) and bulblet diameter (13.282 mm) were measured in outer scales. While incubation temperature of 10-15 degrees C gives the best result for bulblet scale number (3.511 piece), the highest average value for root number of bulblet (3.900 piece) and root length of bulblet (11.224 cm) were measured in auxin dose of 200 ppm IBA.
