أجري البحث بهدف الكشف عن التباينات الشكلية و الجزيئية بين طرز البنج الـذهبي Hyoscyamus
aureus البرية في جنوب سورية، جمعت البذور من سـتة مواقـع و عقّمـت وزرعـت فـي المختبـر
(Vitro In) ، ثم وصفت النباتات النامية في الأنابيب شكلياً بدراسة عدد من الصفات. كما وصفت جزيئيـاً
باستخدام تقنية التكرارات التتابعية البسيطة البينيـة Repeats Sequence Simple Inter) ISSR).
أظهرت النتائج وجود فروق معنوية (p > 05.0) بين النباتات المدروسة باختلاف مواقع الجمـع، إذ راوح
طول النبات بين 97.14 و 97.18 سم و تباين لون الساق بين الأحمر و الأخضر، كما تباينت كثافة الأوبـار
بين المتوسطة و الكثيفة و شديدة الكثافة، و كانت هناك اختلافات كبيرة في أبعاد الأوراق و مساحتها، و راوح طول الجذر الرئيسي بين 09.6 و 37.8 سم. أظهر التوصيف الجزيئي أن العدد الكلي للحزم كان 56 حزمة
منها 49 حزمة ذات تعددية شكلية (بنسبة 5.87 %) نتجت عن استخدام 11 مرئساً غير نـوعي. أظهـر
التحليل العنقودي انفصال نباتات منطقة صلخد بمسافة وراثية قدرها 312.0 ،في حين توضـعت نباتـات
باقي المواقع في عنقود رئيسي انقسم إلى تحت عنقودين، ضـم تحـت العنقـود الأول نباتـات القلمـون
و الديماس بمسافة وراثية 032.0 ، و ضم تحت العنقود الثاني نباتات بصرى التي انفصلت عن نباتات سـد
درعا و وادي الزيدي بمسافة وراثية 017.0 ، مما يعطي مؤشراً أولياً على ارتباط الصفات الوراثية لنباتات
هذا النوع بتوزعها الجغرافي و البيئي.
This research was conducted to detect the morphological and molecular
differences between golden henbane (Hyoscyamus aureus L) collected from
south Syria. Seeds were collected from six locations, then sterilized and grown
In Vitro. Grown plants were described for some morphological characters. The
molecular characterization was carried out using the method of Inter Simple
Sequence Repeats (ISSR) to detect genetic variations. The plants showed
significant (p<0.01) morphological differences among studied locations, Plant
height ranged from 14.97 to 18.97 cm and stem color ranged from red to green.
Trichome density also ranged between medium, high and very high.
Furthermore, significant differences in leaves dimensions were observed
according to the plant geographical location. The main root length ranged from
6.09 to 8.37 cm. Molecular analysis by ISSR produced a total of 56 bands, 49 of
which were polymorphic (87.5%), resulted from using 11 non-specific primers.
A genetic distance dendrogram was drawn. based on the results of genetic
characterization of plant from different locations. The plants collected from
Salkhad separated with a genetic distance of 0.312 while the plants collected
from other locations were grouped together, at the same time, they were
divided into two sub groups, the first group comprised plants collected from
Qalamoun and Dimas regions with a genetic distance of 0.032, whereas sub
group II content Bosra plants which separated clearly from those of Dara' dam
and Wadi Al-Zaidi by a genetic distance of 0.017, These results may indicate a
relationship between genetic characters of this plant species with geographic
distribution.
