هدفت هذه الدراسة لمعرفة أثر المعاملات المختلفة في إنبات بذور الخرنوب للتعرّف على أفضل الطرق الواجب استخدامها و المدة الزمنية المطلوبة، و انعكاس ذلك على نسبة الإنبات و سرعته بحسب المعاملات المطبقة .
أظهرت النتائج بأن خدش البذور كانت الطريقة الأكثر فعالية في زيادة نسبة الإنبات و كذلك معاملة البذور بحمض الكبريت المركز لمدة 30 دقيقة ؛ إذ بلغت نسبة الإنبات 100%، و من ثم المعاملة بالكحول لمدة 60 دقيقة، ثم غمر البذور في الماء الساخن لمدة 60 دقيقة.
أشارت النتائج أيضاً أن سرعة انبات بذور الخرنوب عند معاملتها بالخدش كانت أفضل (14.5Id=) و من ثم المعاملة بحمض الكبريت المركز لمدة 30 دقيقة (21.5 Id=)، و من ثم المعاملة بالكحول (38Id=) عند المعاملة لمدة 60 دقيقة، أما الغمر بالماء الساخن فكانت (60Id=).
The effect of different treatments on carob seed germination was studied.
The results showed that, seed scarification was the most effective method in
increasing germination rate as well as the use of concentrated sulfuric acid for 30 minutes
reaching 100%, followed by the treatment with alcohol for 60 minutes, and immersing
seeds in hot water for 60 minutes.
The results also indicated that the speed of germination when seeds were scarified
was the best (I.D.=14.5), followed by the treatment with concentrated sulfuric acid for 30
minutes (I.D.=21.5), alcohol for 60 minutes (I.D.= 38) and immersing seeds in hot water
for 60 minutes (ID.=60).
