for vegetative propagation of nemaguard, st julien a, tetra and gf677 rootstocks via cutting, two separate experiments were carried out in a factorial based on completely randomized design. semi hardwood cuttings were taken in late august and then treated with concentrations of zero, 1500, 2000, 2500 and 3000 mg/l iba. cuttings were cultured in perlite medium and in a greenhouse with mist syste...
boron (b) toxicity is an important disorder that can limit plant growth in arid and semi-arid environments. it has been proven that use of tolerant rootstocks impede b uptake or transport to the aerial portions of plants. this may alleviate b toxicity in the scion, consequently improves the tolerance to excess b in the root zone. an experiment was conducted to find the effects of b toxicity on ...
به منظور بررسی تحمل چهار پایه از درختان هسته دار به کلروز کمبود آهن، آزمایشی در قالب فاکتوریل بر پایۀ طرح بلوک های کامل تصادفی در چهار تکرار، در دانشکدۀ کشاورزی دانشگاه بوعلی سینا در سال 1391 انجام گرفت. پایه های مورد بررسی شامل هیبرید های هلوو بادام gf677 و gn15، بادام تلخ و هلو و تیمار های غذایی مورد استفاده شامل: محلول غذایی هوگلند فاقد آهن ( اسیدیتۀ 6)؛ محلول غذایی هوگلند حاوی آهن با غلظت 9...
mechanisms of drought stress tolerance of gf677 rootstock, peach and almond hybrid, (prunus persica × prunus amygdalus) were studied under in vitro conditions. plantlets of gf677 rootstock were subcultured into the murashige and skoog (ms) solid proliferation medium containing 1 mg/l ba (6-benzyladenine) and 0.1 mg/l naa (naphthaline acetic acid) in four drought stress levels 0 (control), 10, 2...
Prunus persica L. Batsch, or peach, is one of the most important crops and it is widely established in irrigated arid and semi-arid regions. However, due to variations in the climate and the increased aridity, drought has become a major constraint, causing crop losses worldwide. The use of drought-tolerant rootstocks in modern fruit production appears to be a useful method of alleviating water ...
به منظور ارزیابی اثر تنش شوری بر خصوصیات رویشی و غلظت عناصر غذایی در برگ و ریشه های تعدادی از ژنوتیپ های بادام، آزمایشی با دو عامل ژنوتیپ در چهار سطح شامل ‘شاهرود 12’، ‘تونو’ و ژنوتیپ ’16-1‘ پیوندشده روی پایۀ gf677و پایۀ gf677 و شوری آب آبیاری در پنج سطح شامل غلظت های صفر، 2/1، 4/2، 6/3 و 8/4 گرم در لیتر کلرید سدیم (به ترتیب با هدایت الکتریکی 5/0، 5/2، 9/4، 3/7 و 8/9 دسی زیمنس بر متر) در گلخانۀ...
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...
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...
