The two commercially important apple rootstocks i.e., MM106 and B9 were micropropagated using a liquid culture system. Three different strengths of 0.8% agar solidified PGR free basal MS medium were first tested to optimize the culture media for both the rootstocks. Full strength medium (MS0) supported maximum in vitro growth, multiplication, rooting and survival under field conditions as oppos...

Influence of fructose, sucrose, glucose, sorbitol and maltose carbon sources at various concentrations on rooting and hyperhydricity apple rootstock MM106 was investigated. Type and concentration of sugars had a significant effect on rooting percentage, mean root number, mean root length, hyperhydricity, as well as survival rate. The in vitro cultures produced the higher rooting percentage, mea...

المرفق العام نظرية قضائية من نظريات الاجتهاد الإداري الفرنسي ، حظي باهتمام كبير طرف فقهاء القانون و نظرا لأهميته اعتباره أداة استيراتيجية في يد الحكومات فقد تنبه المشرع الجزائري لذلك وضع له ضوابط إطار قانوني سنة 2015 خلال المرسوم الرئاسي 15 / 247  المتضمن الصفقات العمومية تفويضات ليضبط بعدها اتفاقيات تفويض التنفيذي رقم 18 199 المتعلق بتفويض الذي أصبح مصدر أساس كل اتفاقية تبرم تسيير .

Abstract Experiments were conducted in Ash-Shoubak area of Jordan from June 2003 to September 2005 to study the effect of three apple rootstocks on the development of the small red-belted clearwing borer, Synanthedon myopaeformis (Borkh.) (Lepidoptera: Sesiidae), under field conditions. Mondial Gala apple trees grafted on the dwarfing rootstock M9 and the semi-dwarfing rootstock M26 were equall...
