الملخص هدفت الدراسة إلى تقييم تأثير اضافة السماد الاخضر ومسحوق قشر البيض
الى نظام الزراعة النسيجية المستخدم في استحداث و نمو الكالس لنبات الرجلة
Portulaca oleracea تم تنفيذ التجربة بإستخدام وسط MS مجهز بتركيز مختلفة من (100,50,25) مل/لتر من مستخلص السماد الاخضر و((300,200,100. ملغم / لتر من مسحوق قشر البيض، تم دراسة استحداث الكالس و نموه، إضافة إلى ذلك قياس الوزن الرطب و الجاف و النسبة المئوية للبروتين بعد (60,30) يوم من الزراعة. بينت النتائج ان افضل استجابة لإستحداث الكالس عند المعاملة التي أضيف لها 100 مل / لتر من مستخلص السماد الاخضر و 300 ملغم / لتر من مسحوق قشر البيض حيث ادت الى زيادة مستوى المؤشرات الحيوية الأخرى إذ بلغ أعلى معدل وزن رطب حيث بلغ (3.0 4.0) بعمر (30، 60) يوم على التوالي، أما نسبة البروتين بلغت أعلى قيمة لها عند للمعاملة التي أضيف لها 50 مل / لتر من مستخلص السماد الاخضر و 200 ملغم / لتر من مسحوق قشر البيض حيث بلغت نسبة
(14.08 ، 17.76) بعمر (30، 60) يوم على التوالي.
