This present study was conducted to develop a detailed in vitro propagation
system for the medicinal shrub Capparis spinosa L.
Single nodes with one bud and a small part of stem of 1-1.5 cm long were
used as initial explants which were collected f
rom a shrubs grown under field
conditions at Damascus suburb., (Doumar). Explants were surface-disinfected
by 70% Ethanol for 1 min., followed by immersion in Sodium Hypochlorite or
HgCl2 for different periods and concentrations with 1 drop of Tween 20 for 100
ml disinfectant solution, where after, they were placed onto MS basal medium
containing a combination of growth regulators at different concentrations (BA
at 4.44 or 8.88 μM) each with IBA 0.49 μM. Cultures were incubated in the
growth room at 23±1 c and light intensity of 3000 lux at the cultures level.
Multiplication rate of 25.17-fold from one explant was achieved every 4 weeks
on the optimal MS medium (MS+8.88μM BA+0.49μM IBA).
The described method has potential to produce large numbers of plantlets
within a short period of time to expand its cultivation for medicinal uses.
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%.
