نفذت عدة تجارب مخبرية لتقويم استجابة عشر سلالات (أكساد) من القمح الطري، و أخرى من القمـح
القاسي لتحمل الإجهاد الملحي (NaCl) في طور البادرة الفتية. استخدمت تقانة الاستجابة للتحريض الملحـي
في سبر التباين الوراثي لتحمل الإجهاد الملحي ضمن سلالات أكساد. و تم أيضاً تقويم تأثير طبيعة التحـريض
في تحمل البادرات المحرضة للمستويات المميتة من الإجهادات غير الإحيائية (الملوحة و الجفاف).
Several laboratory experiments were conducted to evaluate the response of
ten ACSAD durum and bread wheat landraces to salinity stress tolerance at
seedling stage. The salinity induction response technique was applied to assess
the genetic variability, and the effect of induction nature in improving the
tolerance to lethal levels of some abiotic stresses (drought and salinity). The
applied screening tool was rapid and efficient in assessing the genetic
variability for the response of studied durum and bread wheat landraces to
salinity stress tolerance.
