Biostimulators may open new avenues for alternative cultivation technologies for ornamentals. Dwarfing makes it possible to use new species and varieties in public areas. They can also be used as potted ornamental plants. During dwarfing, the habizus is more bushy and the internodes are shortened, which is commercially advantageous. Matthiola incana (L.) R. Br. is an annual ornamental plant, which, although less significant in Hungary, is still bred and marketed by many companies worldwide. The effects of Bistep and thigmomorphogenesis are investigated in different ways with ‘Bona’, ‘Hala’ and ‘Mela’ cultivars of the Varsovia cultivar group. As a result of our measurements in previous years, that mechanical stress are proved by affects the morphological properties of plants, and the Bistep biostimulator strengthens the organ properties of the plant. In summary, in the case of the biostimulator-treated group, it was observed for several cultivars that the vegetative parameters produced significantly higher values than in the case of the control groups. Mechanical stress treatments significantly reduced the size of fresh root mass in all three cultivars compared to the control groups. It can be concluded that mechanical stimulation can be used in a greenhouse environment to change the growth rate and to produce marketable plants.
