The effects of the concentration of the inorganic base of Murashige-Skoog (MS) media and synthetic plant growth regulators (PGR) – cytokinins (kinetin, 6-BAP or thidiazuron) with IAA – on Cymbidium hybrid organogenesis in vitro are presented. In the experiment with varying concentrations of the MS mineral base we revealed that the growth of shoots was maximal on the complete MS medium, whereas rooting and pseudobulbs formation – on 1/2 MS. In the combined PGR and auxin treatments the best effect on the formation of pseudobulbs in the Cymbidium hybrid was achieved in media supplemented with 2.5 mg/l kinetin + 0.5 mg/l IAA (pseudobulbs number) and 0.1 mg/l kinetin + 0.5 mg/l IAA (pseudobulbs size). The number of newly formed shoots was maximal on the medium supplemented with 10^-4 mol/l thidiazuron + 0.5 mg/l IAA, whereas the longest shoots formed on media supplemented with 6BAP + IAA (0.5 mg/l each).
