أظهرت النتائج أن التنضيد البارد الرطب لمدة 15 يوماً ( على درجة حرارة 4-5 م°) لبذور الصنوبر الكناري قد أعطى أعلى نسبة إنبات وصلت إلى (91.11)% , تلته نسبة إنبات معاملة النقع بحمض الجبرليك بتركيز 300 جزء بالمليون لمدة 20 دقيقة (82.22%) ، و لم تكن الفروق معنوية بينهما ، في حين أعطت المعاملات الأخرى و هي التنضيد البارد الرطب لمدة 30 يوماً (على درجة حرارة 4-5 م°) ، و النقع بماء الصنبور لمدة 48 ساعة ، و الشاهد نسب إنبات أدنى , و لكنها أعلى من 60%. لقد تفوقت معنوياً معاملة النقع بحمض الجبريليك في سرعة الإنبات (2.32 يوماً \ بذرة ) على كافة المعاملات, و في درجة التجانس ً (4.39 بذرة \ يوم ) على كل من معاملة النقع بماء الصنبور و الشاهد ، و لم تتفوق معنوياً على معاملة التنضيد البارد.
The results shows that, the cold wet of Canary pine seeds stratification for 15 days at (4-5c◦),gave higher germination percentage( 91.11%). The treatment of soaking seeds with superiority was not significant. Other treatments; the cold wet stratification of seed for(30) days at(4-5c◦), soaking seeds with tap water for (48 h.) and the control, all gave lower germination percentages, but still higher than (60%). The treatment of soaking seeds with GA had significant superiority in the speed of germination (2.32 day ∕ seed), but it was not significant with the cold wet stratification.

This research aims study the effect of different treatments in activate and increase
percentage of germination Cupressus arizonicaL.seeds to use plants in forestation projects,
seeds were get from mature conifers, and tested by different treatments
with control, then
cultured within polyethylene bags many times to calculate indicators of germination. The
results showed that the soaking the seeds Cupressus arizonicaL. in citric acid 0.1% with
cold wet stratification for 30 days at 4-5c gave higher germination percentage 75%.The
treatments of the soaking seeds in sulfuric acid0.1% and hydroxide sodium 0.1% with cold
wet stratification for 30 days gave respectively 60%-53% .But superiority was not
significant. Other treatments; soaking the seeds in tap water 24h with cold wet
stratification for 30 days gave only 36%.But the control treatment gave lower germination
percentage of all just only 9%.
The treatment of soaking seeds in citric acid 0.1% with cold wet stratification for 30
days surpassed the rest of the treatments in effect on plant height at the end of the
experiment.
The effect of different treatments on carob seed germination was studied.
The results showed that, seed scarification was the most effective method in
increasing germination rate as well as the use of concentrated sulfuric acid for 30 minutes
reac
hing 100%, followed by the treatment with alcohol for 60 minutes, and immersing
seeds in hot water for 60 minutes.
The results also indicated that the speed of germination when seeds were scarified
was the best (I.D.=14.5), followed by the treatment with concentrated sulfuric acid for 30
minutes (I.D.=21.5), alcohol for 60 minutes (I.D.= 38) and immersing seeds in hot water
for 60 minutes (ID.=60).
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 .
This study was carried out at three different forest sites in Syria in order to
determine the effect of changing rainfall, temperature and soil on kernel
productivity of stone pine (Pinus pinea L.)> these sites included: Jabal Alnabi
Mata, (Tartou
s province, L1), Dahr Alkhoser (Homs province, L2) and E′en
Jron site (Idleb province, L3). Results showed that kernel productivity of stone
pine per tree was 236.3, 252.8, 143 g per tree, and 177, 162.3, and 86.98 kg per
hectare in L1, L2, and L3, respectively. These differences were attributed due
to the variation in the composition, textured and fertility of the soil available in
the three locations studied. It was concluded that trees of stone pine grow better
and superior in Kernel productivity in humid and super-humid bioclimatic
zone.
The experiment was carried out to assess the germinability and seedling
growth rate of some treated vegetable seeds (i.e. onion, carrot, and tomato) with
aerated - aqueous solutions.
Seeds were treated for 24 hours with 0.1% of both succinic acid
and
nutrient solution, and the seeds to medium ratio was 1:5.
The soaking solution was continuously aerated by an air pump. At the end
of treatment, the seeds were dried up at room temperature to eliminate the
excess superficial moisture.
