أظهرت الدراسة أن العقل المعاملة بالأوكسين IAA جذرت بشكل مبكر و تأخر تبرعمها. من جهة أخرى، أدت المعاملة بالهرمون IAA إلى زيادة نسبة التجذير و خفضت من نسبة التبرعم. كما تبين أن زيادة الملوحة حتى ٠,١ مولر خفض من القدرة على التجذير، في حين أن استخدام أندول حمض الخليك قلل من التأثير السيئ للملوحة. و قد تم الحصول على أفضل صفات للتجذير في المعاملة ذات التركيز المعتدل ( ٠,٠٥ مولر).
The study showed that IAA treated cuttings were rooted earlier and bud development was delayed. On the other hand, IAA treatment increased rooting percentage and reduced the percentage of bud development. Increasing NaCl salinity to ٠,١ M decreased the rooting ability in cuttings, while the use of IAA could mitigate the adverse effect of salinity. The best results of rooting were obtained in treatment of (٠,٠٥ M).

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%.
Semi-wooden cuttings of two - jujuba cultivars were vegetitirely propagated
under greenhouse conditions, by using different concentrations of Indole
butyric acid (IBA), at Hanadi Research Station, Lattakia.
The rooting percentage reached 71.3% aft
er two months for the Ziziphus
jujube mill, and 83.3% for the Ziziphus jujube tayan tsizao, when they were
treated with 4000 mg/L of (IBA) for five seconds while the rooting percentage
was zero for the non-treated cuttings (Control) .
In this study, the effect of different concentrations of sodium chloride
(NaCl) (0, 50, 100, 150 mM) on some physiological characteristics and some
growth indicators of SO4 grape rootstock propagated in vitro was studied at the
laboratories of Gen
eral Commission for Scientific Agricultural Research
(GCSAR), Damascus/Syria. Results indicated that the increase of NaCl
concentration up to 100 mM in culture medium led to reduce the growth
indicators (survival plants, average of the plant length and average number of
buds) with significant differences when compared with the control plants after
4 weeks from culturing on multiplication media, while treatment with 150 mM
of sodium chloride led to death of all plants. Using the concentrations 50 and
100 mM of NaCl also caused decreasing the total chlorophyll content in the
leaves.
This Research Deals With Studying Of Five Concentrations in IBA Auxin
(0.25 – 0.5 – 0.75 – 1 – 2 mg\ l ) And Control Medium For Rooted Plantlets To Wild
Apple (Malus trilobata Lab.) By Plantlets Cultured It's Length (1.5-2) cm On Half-
Strength Mu
rashige And Skoog Medium(½MS), Then Making Rooted Percentile And
Mean Of Number And Length Of Roots, The Result Was: The First Treatments (0.25 mg\l)
Were Significantly Better Than Other Treatments And Control For About Rooted
Percentile (64%) And Mean Of Number Roots (16 Roots), The Third Treatments (0.75
mg\l) Were Significantly Better Than Other Treatments For About Mean Of Length Of
Roots(21.03)cm.
Despite being one of the reasons of production decline, salinity is still a tool
to improve production quality in some hybrids. this research was conducted at
the Faculty of Agriculture, University of Damascus during 2012 season. A salt
stress was
applied on two tomato hybrids, Bonaparte and Marmara by
increasing the value of the electrical conductivity of irrigating water from 4 to
13 ds / m, at the stage of the third true leaf to the end of growth of the two
tomato plants.
Results indicated that salt stress led to a reduction in the fruit weight of
both hybrids but it helped in improving some chemical and physical
characteristics relating to fruit quality, such as increasing the fruit content of
soluble solids in both hybrids. Salt stress did not affect the lycopene content of
fruits in Bonapart, but it was increased by 2 folds inMarmara. Some fruit color
indices (a* and b*) were greater in Bonaparte while L* indice was higher in
Marmara. However, the color indices of fruits were not affected by salinity in
both hybrids studied.
