جرى وضع تَِقانة للتكاثر الخضري الدقيق بتضاعف البراعم لخمسة أصناف من نخيل الَتمر هي:
الخلاص، الهِلالي، الصْفري، الزهدي، و الرزيز. و تشمل هذه التَِقانة خمس مراحل هي: الزراعة الأولية،
تكوين البراعم الجانبية، إكثار البراعم و استطالتها، تجذير النموات داخل الأنابيب و أخيرًا أَْقَلمة النباتات
الناتجة (نقل النباتات إلى الأحوال الطبيعية). و في هذا البحث، جرى وصف سائر الشروط و الأوساط
الغذائية المستعملة لمراحل الإكثار كافة. و قد تم الحصول على نباتات كاملة من سائر الأصناف المدروسة.
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).

Commission for Scientific Agricultural Research (GCSAR), Damascus with the
aim of in vitro vegetatively micropropagation using some plant growth
regulators on multiplication
The objective of this research isto study the in vitro effect of some plant hormones
(growth regulators) BAP,NAA, 2,4-D, and genotype on callus and bud formation from
embryonic axes of two Soybean cultivar seeds (sb-44, sb-172).
The embryonic axes
This study was carried out at AL-Rasheedia Agricultural Research Station
,Ninevah, to evaluate five radish cultivars, during fall seasons (1997-1998) and
(1998-1999) .
Results showed significant differences among the different cultivars. The
cult
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).
A detailed in vitro multiplication system for rapid micropropagataion of the
Hypericum perforatum L. has been developed. Shoot tips and axillary buds
excised from this plant which were collected from Tartous explants and surface
disinifected then cultured on MS (Murashige and Skoog 1962) medium.
