Micropropagation of Calathea ornata Koern.
- 1 Research Institute of Pomology and Floriculture, Skierniewice, Poland
In vitro cultures of Calathea ornata Koern. cv. Sanderiana shoots were maintained on modified medium of Murashige and Skoog. With the aim to find effective micropropagation method the effects of cytokinins, paclobutrazol, saccharose, mineral salts and shoot-tip damage on the shoot growth and quality were studied. The highest number of shoots was obtained on a medium containing 2.5 mg dm-3 benzylaminopurine, 2.5 mg dm-3 kinetin, 4.5 % saccharose and raised concentrations of Ca, Mg, Fe and Mn. Shoot branching was markedly stimulated by the shoot-tip damage.
Keywords: cytokinins; mineral composition; paclobutrazol; saccharose
