درس تأثير استخدام العقل نصف المتخشبة المأخوذة من أعمار مختلفة من أشجار الماغنوليا كبيرة الأزهار. Magnolia grandiflora L ( أشجار فتية بعمر 15 سنة, أشجار متوسطة العمر 30 سنة, و شجرة كبيرة عملاقة بعمر 110 سنة), و معاملتها بهرمون أندول حمض البيوتريك ( IBA ), بتركيز ppm 2000, بثلاثة أزمنة (10-20-30 ثانية) تحت ظروف البيت المحمي.
Studying of using of semi-hardwood cuttings that were got from different ages for Magnolia gradiflora L. trees: Young trees that are 15 years old, middle-aged trees that are 30 years old, and only one old giant tree which is 110 years old were performed by treating the cuttings with Indole Butric Acid Rooting Hormone 2000 P.P.M. which was used during three periods of time: 10, 20 ,and 30 seconds under green house conditions.

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.
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) .
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.
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.
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.
