The aim of this study was to evaluate the effect of microbiological products Trihodermīns and Vitmīns on scale promotion and bulblet development in lilies. In September, 2010, bulbs from the Lilium collection of the Latvia University of Agriculture were harvested and used for scale bulblet induction. Three cultivars from three groups: Asiatic hybrid ‘Vīgante’, the Longiflorum × Asiatic hybrid ‘Sonora’ and the Trumpet hybrid ‘Elēģija’ were used as plant material. Scales were treated in three ways: 1) untreated control; 2) Vitmīns solution (10 ml LE-1) and 3) Vitmīns solution plus Trihodermīns dry powder form (10 g kgE-1), added to peat moss. The scales were kept in polyethylene bags and incubated in the greenhouse at 18±2 °C for 12 weeks; in the refrigerator at 5±2 °C for 10 weeks and 18±2 °C for 4 weeks. The effectiveness of microbiological products was evaluated by the number of bulblets per scale, the diameter of bulblets, leaf height, root length, and the percentage of dead plants. The coefficient of variation for the number of bulblets per scale was recorded in the range from 19.7 to 39.2%. The treatment with Vitmīns plus Trihodermīns resulted in a significantly higher number of bulblets per scale (P is less than 0.05 vs. control).
