This study was carried out in nine sites of various altitudes. The sites represent
scattered zones of Cordia myxa Forsk. as an introduced species in the coastal region,
Lattakia governorate during 2010-2011. The research showed that there is an eff
ect of
altitude on the investigated trees in the different sites, and that there were significant
differences in relation to the characteristics of the average of the following: tree height,
length of leaf stalk, catkin length, canopy, fresh and dry leaf weight, and fruit weight.
However, there were no effects of altitude on the species. There were also no observed
significant differences in relation to the characteristics of the average of the following: the
tree diameter, trunk length, flower number in one catkin, leaf length, leaf width, leaf area,
leaf humidity percentage, flowering start, and flowering period. It can be said that there
were changes in the morphological characteristics of the studied trees in the different sites,
which appeared to be a preliminary indication of the impact of altitude on the variations of
some morphological characteristics of Cordia myxa Forsk.
This study was carried out during 2014-2015 in two different nurseries located in
University nursery (Lattakia governorate) and Salhab nursery (countryside of Hama
governorate). Seeds were taken from two sites of Lattakia governorate (Mashqita– Bsn
ada)
where Cordia myxa exists as exotic species in some coastal regions and three treatments in
addition to control were examined .The results showed that there is an effect of
scarification of seeds on investigated treatments and were significant differences in
germination percentage in both sites which recorded 55% in university nursery and 35% in
Al-Ghab nursery. While there were not contrast between the soaking in boiling and tap
water treatments on the seed germination energy in Al-Ghab nursery. Scarification
treatment gave higher value of germination energy 25% in Al-Ghab nursery and 21.66% in
university nursery , while the same treatment decreased germination velocity compared to
other treatments in university nursery which seed needed in average ( 8,01 day) whereas
the same treatment increased germination velocity in Al-Ghab nursery which needed (1,54
day). Finally, regarding to cutting ,There is not observe to any positive influence to
cuttings which treated in ABA hormone (1g/l) for (10,20,30 m). It could be deduced that
there were changes in germination percentage, germination energy and germination
velocity in two sites which appeared to be a Preliminary indication of impact of the some
dormancy breaking treatments on investigated indications of Cordia myxa Forsk. species .
