In order to evaluate the tolerance of some almond genotypes to salinity a pot experiment was carried out with 3 factors cultivar in 11 levels including Touno, Nonparaeil, Mamaie, Shokofeh, Sahand, Fragness, 1- 16, 1-25, A200,13-40 and GF677 and salinity in five levels including 0, 1.2, 2.4, 3.6 and 4.8 g/l of sodium chloride with electrical conductivity 0.5, 2.5, 4.9, 7.3 and 9.8 ds/m, respecti...
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 ...
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...
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...
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...
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...
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...
بادام، prunus dulcis mill، از قدیمی ترین محصولات خشکبار بوده که امروزه بیشترین سهم از تولید خشکبار جهان را در بر می گیرد. بادام مصارف خوراکی، صنعتی و آرایشی دارد و در داروسازی از روغن آن استفاده می شود. از زمان های قدیم در منطقه های خشک افزایش بادام تنها از راه بذر صورت می گرفت. پس از مرسوم شدن پیوند نیز از دانهال ها به عنوان پایه استفاده می شد. امروزه اصلاح پایه های درختان میوه همگام با اصلاح ...
Among abiotic stresses, soil and water salinity are the major factors affecting agricultural crops growth and productivity worldwide. On the other hand, the scion-rootstock combination and also foliar application of chimical compounds as salicylic acid can affect the nutrient elements content of almond leaf under salinity conditions. Therefore, in this study, the effects of foliar application o...
In order to investigate the effect of putrescine and auxin (IBA) on rooting of semi-hardwood cuttings of the GN15 hybrid rootstocks, an experiment was conducted at the Flower Biology Laboratory of Faculty of Agriculture, Tabriz University in 1994. Cuttings were obtained from Sahand Gardening Research Station. This experiment was conducted in a completely randomized design with four replications...
