The research was carried out during 2014 and 2015 agricutural
season ,To study the effect of spraying cytokinin regulator on
vigitative and fruiting charachterstics cotton plant.
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 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.
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) .
The study was conducted at the growing season 2009 in one of an orchard
in Abu-Al-Khaseeb region – Basrah, studied the effects of spraying of GA3
concentration of 25 mg. l-1 and spraying of liquorice extract concentration (5,
10) g.l-1 and sprayin
g of Roselle extract concentration (15, 20) g.l-1 as well as
compared treatment (spraying with distilled water) in two stage hbabok and
Kemri on fruit drop and qualities of Braim cultivar, showed results that the
spray in hababok stage and treatment of GA3 concentration 25 mg.l-1 increased
of weight and size of the fruit significantly and did not show significant
differences between the spray at the stage of hababok and Kemri in influencing
the T.S.S., while treatment of spraying liquorice extract concentration of 5 gm.l-
1 increased total soluble solids and dry matter significantly, werever spraying at
the stage of Kemri with GA3 increased significantly in water content of fruits,
while sprarying in hababok stage increased in dry matter content of the fruits
and did not show significant differences between the results of treatments or
the stage of spraying in effect of Drop fruits for a cultivar of Braim through the
stages of growth and maturity (Khalal, Rutab and Tammar) this results
confirms that the phenomenon of drop fruit under the influence of genetic type
male and female cultivar.
