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.
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.
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%.
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.
