This study has been conducted to show the influence of some factors to the
rooting of semi-wooden cuttings of boxwood Boxus suffruticosa L. in order to
know the best concentration of indol biotryc acid (IBA) and the best rooting
media for the root
ing of boxwood cuttings .
The experiment was designed in the sub-plots method and semi-wooden
Boxwood cuttings were used. The cuttings were treated with three
concentrations of IBA: 3000, 5000, 10000 p.p.m. using fast dipping. Then the
cuttings were planted (distributed) in five rooting media, namely: sand, peatmoss,
khaffan, (sand+peat-moss) in the rate of (1:1), (khaffan+ perlite) in the
rate of 1:5 respectively. under protected conditions. The experiment has
continued for 8 weeks.
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%.
Some factors which affect in vitro propagation of sour orange (Citrus
aurantium. L.) were studied on Murashige and Skoog medium. Medium
containing ١,٠ mg/L ٦-Benzylaminopurine (BA) was satisfactory for shoot
multiplication, Dichlorophenoxyacetic acid (٢،٤-D) was not effective for shoot
proliferation and it enhanced callus formation.
