• Resumen

  • Plants, as part of the ecological system, may find themselves in danger of various unfortunate circumstances due to their sessile nature, climate change and other human interventions/factors. Inappropriate agricultural or forestry practices, habitat destruction attributable to excessive urbanization, uncontrolled harvesting, pollution and the spread of invasive species that compete with the native ones are the main factors leading to ecological collapse. The careful protection and preservation of biodiversity is based on different conservation methods. Ex situ methods involve the protection of endangered taxa outside of their natural habitat that necessitate the location, sampling and transfer of the species in question. These are the most convenient, cost effective methods known today. In vitro plant micropropagation gives a possibility to keep alive special lines with genetic identity for conservation purposes, to multiply endangered plant species for repatriation, or producing large plant biomass for yielding secondary metabolites. In Hungary, Dianthus are classified as a protected or strictly protected species, consequently, creating a successful conservation strategy is indispensable. Therefore, different types of cytokinins (aromatic and isoprenoid side chain containing and synthetic cytokinins) applied alone or in combination were tested to determine the optimal plant growth regulator for the multiplication phase of the in vitro micropropagation of the species.
