This study aimed to investigate Four levels of IBA concentration: (0
(control), 1000, 2000, 4000 ppm) and three kinds of rooting media: sand,
peatmoss, sand+sawdust in ratio of 1:1 in a factorial complete random design.
The results indicated that
the concentration of 2000 ppm was superior at
rooting percentage 76%, root number (20 roots) and root length 13 cm over the
other levels of concentration. Besides, the media of (Sand+Sawdust) was
superior at rooting percentage 72%, rooting number (19 roots), root length 11
cm, physical and chemical charactaristics and the charactaristics of the rooted
cuttings.
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%.
