Gardenia jasminoides is considered as a plant of tropical and suptrofical regions. This plant has a great importance in Germany and Syria. Despite that this research has been done in Germany, it is possible to generalize it for Syria as it was conducted in stable laboratory conditions. The experiment was conducted in the environment of greenhouse no. 5 at the Higher Gardening Institute- Branch of Ornamental plants in Berlin. Cuttings imported from Denmark were used after being stored in an atmosphere of high relative humidity reaching 95-100%.
