Abstract AR
تم تقدير حامض الابسيسك (ABA) الحر و المرتبط في بذور اللوز المر للصنف المحلي بدام من بساتين منطقة السليمانية Prunus amygdalus L.
باستخدام تقنية الـ TLC و استعمال جهاز الـ HPLC خلال فترات التنضيد (صفر و 15 و 30 و 45 و 60 يوم) و التحقق في نسبة الإنبات و التي أجريت في مختبر الهرمونات النباتية لقسم الإنتاج النباتي في كلية الزراعة للجامعة الأردنية, عمان, الأردن خلال الفترة 2004 و 2005.
دلت النتائج أن التنضيد البارد إلى أدى إلى انخفاض معنوي في محتوى حامض الابسيسك (ABA) في البذور و الغلاف الاندوكاربي و كان الانخفاض الحاد في تركيز حامض الابسيسك خلا الخمسة عشر يوم الأولى من عملية التنضيد و خصوصا في المدة 45 يوم تنضيد و بعدها استمر التركيز في الانخفاض.
إن انخفاض مستوى حامض الابسيسك خلال عملية التنضيد كان ذات علاقة بزيادة نسبة الإنبات و خاصة عند مدة التنضيد 45 يوم و التي بلغت نسبة الإنبات عندها 85.33%%.
Abstract EN
Endogenous concentrations of free and bound abscisic acid (ABA) in bitter almond seeds Badam variety (local variety) from Sulaimania orchards Prunus amygdalus L.
were determined by TLC and HPLC during various periods of cold stratification (0, 15, 30, 45, and 60 days) and the germination was investigated at the Plant Hormones Laboratory in the Department of Plant Production, Faculty of Agriculture, University of Jordan, Amman, Jordan, during the period 2004 to 2005.
The results indicated that cold stratification n(at 5 ºC using perforated polyethylene bags filled with moistened perlite) significantly reduced abscise acid (ABA) contents of the seeds and their endocarps.
A sharp significantly decline in ABA was observed during the first 15 days, especially in 45 days, after that the decline was completely decreased.
The reduction in the level of ABA during stratification was associated with significantly increased germination percentage especially for 45 days 85.133 %.
