introduction: salinity is the most significant abiotic factor limiting crop productivity and several physiological responses, including modification of ion balance, water status, mineral nutrition, stomatal behavior, photosynthetic efficiency and so on. the gf677 (prunuspersica×prunusamygdalus) is widelyusedas rootstock for peach and almond. it is mainly used as a rootstock because of its resis...

آلیاژهای منیزیم معمولاً دارای عدم تقارن تسلیم در حالت کشش و فشار هستند که این عامل ناشی از سازوکارهای مختلف تغییر شکل پلاستیک فعال تحت بارگذاری‌های کششی فشاری است. مقاله بر روی شبیه‌سازی المان حجمی نماینده‌ی سه‌بعدی آلیاژ اکسترود شده تمرکز دارد تا با کمک روابط کریستال پلاستیسیته تأثیر شدت بافت پایه ـ را بررسی کند. پلاستیسته مبتنی‌بر لغزش به‌صورت یک زیربرنامه نرم‌افزار آباکوس (U‌M‌A‌T) برای آزمون...

in order to evaluate tolerance of four prunus rootstocks to fe-deficiency-induced chlorosis,  an experiment was carried out in bu-ali sina university in 2012 using a rcbd design with four replications. four rootstocks were used, including gf677, gn15, bitter almond and peach and nutritional treatments were: hoagland solution without fe (ph = 6), hoagland solution containing 90µm fe as control (...

the gf677 (prunus amygdalus×prunus persica) is a peach rootstock tolerant to fe deficiency .therefore, mass propagation of gf677 rootstock is recommended by bioreactor. on the other hand, plant micro-propagation using bioreactors can decrease the cost of production and makes it an economical method. in this research, the possibility of using bioreactor and optimization of the tissue culture pro...

abstract in vitro leaf explants of gf677 hybrid rootstock and rabi cultivar were placed on mql medium supplemented with bap at 0, 1, 2, 3 and 4 mg/l and naa at 0, 0.15 and 0.3 mg/l concentrations. the results revealed that bap, naa, genotype and their interactions had significant effect on both percentage and mean number of the regenerated shoots. for gf677, the highest percentage of shoot rege...
