This research was conducated on Ceratonia siliqua L. in vitro to study the effect of
some growth regulators in both multiplication and rooting stage. And determine the best
concentrations wich lead the highest rate of multiplication (interms of number of shoots
and length), and the best rooting (interms of percentage of rooting, number of roots and
length).
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 cond
ucted 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%.
