The present study was conducted on aerial offshoots of date palm
Berhi cultivar after separation from their mother trees, their bases were
dipped in solution of plant growth regulator (IBA).
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.
Tissue culture process of date palm propagation via bud proliferation is
fully described. Adventitious plantlets were obtained from shoot tips. axillary
buds and the bottom of young leaves of five date palm cultivars (Sefri, Zahdi,
Rizzez, Khalas
and Hillaly).
