أُجريت التجارب على العقل المتخشبة المأخوذة من أشجار مؤنثة للكيوي، صنف هايوارد، باستخدام منظّمات النّمو النباتيّة، في مركز البحوث العلمية الزراعية باللاذقية خلال الأعوام (2009 و2011 و2012). وتمّ اعتماد موعدين لجمع العقل ( كانون الثاني/يناير، و شباط/فبراير). قُسّمت العقل في كلّ موعد إلى ثلاث مجموعات؛ حسب موقع العقلة من الفرع (قاعدية، وسطية، و طرفية). تمّ استعمال منظّمات النمو (NAA- IBA) بعدة تراكيز لكلٍّ منها، بالإضافة لمعاملتي خليط من المنظمين معاً.
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 (January 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 was conducted at the Agriculture Faculty, Damascus
university to determine some factors affecting rooting of some grape rootstocks
(B41, Ru140, SO4) by hardwood cutting during two subsequent seasons. The
results showed that Rooting p
ercentage ranged between 50 to 65%. with
significant differences between tested rootstocks. The highest rooting
percentage was obtained on B41 rootstock reached 65.47% followed by SO4
and then by Ru140 which gave the lowest percentage 50.44%. The treatment
with hormone IBA increased rooting proportion and all the parameters
(number and length of root, number of leaves and shoot length) were
significantly higher than parallel parameters of the control. The storage of
cuttings at 4°C for 50 days increased significantly proportion of rooting and
number of roots compared with the storage under field condition. There were
significant differences among dates of planting where the third date (mid
February) showed superiority in all parameters studied over other dates. The
cuttings from basal and middle of annual growth gave a significant superiority
in the average root length (5.26–4.32 cm, successively) compared to the
terminal cuttings while there was no significant effect to the cuttings position on
rooting proportion.
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) .
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.
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 root
ing 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.
