جاءت هذه الدراسة لتوضيح تأثير بعض العوامل في تجذير العقل نصف المتخشبة لنبـات الشمـشير بهدف معرفة التركيز الأنسب من أوكسين أندول حمض البيوتريك (IBA) و أفضل وسط زراعـي لتجـذير عقل نبات الشمشير نصف المتخشبة. صممت التجربة بطريقة القطع المنشقة و استخدمت عقل نصف متخشبة من الشمشير، حيث عوملـت بثلاثة تراكيز من أوكسين أندول حمض بيوترك (IBA :(10000 ،5000 ،3000 جزء بالمليون m.p.p . بطريقة الغمر السريع، و وزعت ضمن خمسة أوساط زراعية هي: الرمل، بتموس، خفان بركاني أسـود، رمل+بتموس بنسبة 1:1 ،خفان+برليت بنسبة 1:5 على التوالي تم التجذير في جو من الـري الـضبابي المتقطع أوتوماتيكياً، و ضمن ظروف الزراعة المحمية، و استمرت التجربة مدة 8 أسابيع.
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 rooting 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.

This study aimed to investigate Four levels of IBA concentration: (0
(control), 1000, 2000, 4000 ppm) and three kinds of rooting media: sand,
peatmoss, sand+sawdust in ratio of 1:1 in a factorial complete random design.
The results indicated that
the concentration of 2000 ppm was superior at
rooting percentage 76%, root number (20 roots) and root length 13 cm over the
other levels of concentration. Besides, the media of (Sand+Sawdust) was
superior at rooting percentage 72%, rooting number (19 roots), root length 11
cm, physical and chemical charactaristics and the charactaristics of the rooted
cuttings.
This study was conducted at glasshouse of Citrus and Tropical Research Department
in Tartus governorate, and Olive Nursery in Latakia governorate, during 2015 to
determine the influence of Indol-3-Butyric Acid (IBA) doses on hardwood and
softwood
top cuttings of three types of M. alba L. (B-1, B-5, KH-8) and three types
of M. nigra L. (M-4, KH-9, KH-1) and one fruitless type (B-3), which spreads
in different locations in Tartus, Syria. Hardwood cuttings were prepared during
February from one-year-old shoots, and the softwood top cuttings were prepared
during August in 2015. The cuttings were treated with different doses of IBA (1000,
2000 and 4000 ppm) in addition to the control application 0 ppm. The cuttings were
planted in the glasshouses in order to root.
Jasminum sambac, or Arabian jasmine is one of the most important
Jasminum species in perfume industry. It is an ornamental evergreen erect
shrub. Flowering date starts from the early May till the end of October. Syrian
climate is very suitable for
the growth and the flowering of the shrub, therefore
the study was carried aut to investigate the effect of some major factors on
rooting of semi-hard wood cuttings.
A study on the propagation of female kiwi trees (Hayward variety) by wooden
cuttings, using plant growth regulators, was conducted at Latakia Agricultural
Research Centre during the seasons 2009, 2011 and 2012. Two dates for collecting
cuttings (J
anuary and February) from kiwi trees which were selected. On each date,
the cuttings were divided into three groups according to cutting location on the
shoot (basal, middle and apical). The NAA and IBA growth regulators were applied
at several concentrations, in addition to two treatments of the mixture of both growth
regulators.
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.
