The research focused on the effect of GA₃ and BA on the yield of Allium karataviense ‘Ivory Queen’. The substances in concentration of 500 mg₃·dm⁻³ were applied in the form of a 60-minute bulb soaking prior to planting or plant spraying in the green bud phase. It was discovered that GA₃ applied in the both forms causes the inflorescence shoot elongation and the increased number of flowers in inflorescence, and increases the total yield expressed in the bulb weight. When applied in the form of plant spraying, it increases the number of bulbs in the total yield. Plant spraying with BA leads to the production of a greater number of flowers in inflorescence. BA application in the both forms increases the total yield expressed in the bulb weight.

In years 2005-2007 the usefulness of Allium christophii TRAUTV., A. neapolitanum CIRILLO, A. ’Purple Sensation’ and Nectaroscordum siculum (UCRIA) LINDL. was assessed for delayed culture for cut flowers, and of A.’ Ivory Queen’ as a potted plant. The bulbs were forced in the greenhouse in two years, from the first half of May (8 May 2005, 4 May 2006 and 11 May 2007) and from the first half of June (5 June 2005, 1 June 2006 and 8 June 2007). Allium ’Purple Sensation’ and N. siculum were forced only in 2007. In autumn and winter the bulbs were kept indoors at a temperature of 20°C. Then, 16 and 18 weeks before the start of forcing, the bulbs were planted and cooled indoors at 5°C and 2°C. An exception was A. neapolitanum, whose bulbs were first dry-cooled and then planted 4 weeks before transferring them to the greenhouse. On the basis of obtained results, it can be stated that the taxa useful in delayed culture for cut flowers include A. christophii and A. neapolitanum, and A. ’Ivory Queen’ as a potted plant. Cooling of the bulbs should last 18 weeks and start in the first half of May.
