to better understand seed priming that improve seed germination and seedling uniformity, we examined the physiological role of osmopriming in germination of bread wheat (triticum aestivum l.) seed embryos by a proteomic approach. for this purpose, we used two systems. the first system consisted of osmo-primed seeds by peg 6000 at -0.8 mpa at 15?c for 24 hours, followed by air drying at 15?c, an...

In this paper, we studied polyetheneglycol (PEG) pretreatment effect on the mature embryo culture in vitro by using barley (Hordeum vulgare L.) seeds. Meanwhile, we analyzed and assayed its mineral element and endogenous hormone level. The experimental results were as follows: (1) PEG-6000 imbibition could obviously slow down the water timecourse absorbed by barley seeds; (2) 10% PEG-6000 treat...

Priming fresh and naturally aged canola seeds with different substances observing the seed germination properties are involved in this work. Fresh of cv. “süzer” were treated distilled water, -0.8 MPa polyethylene glycol (PEG) 6000 50 mM thiamine for 8 hours. Storage showed loss capacity compared to seeds. Present findings indicate that priming can improve speed both canola. Germination percent...

Drought, salinization and heavy metal pollution of soils are main stress factors with an increasing impact on the deterioration soil quality, yield crop quality. Seed priming shows good results in improving seed germination, seedling growth plant development. Proline (Pro) metyl jasmonate (MeJA) show stimulating activity help plants overcome stress. The study investigated effect Pro, MeJA hydro...

to answer this question that if osmopriming improve germination indices in salinity-affected seeds of pinus eldarica medw., a factorial experiment in randomized completely design was carried out with three replications. osmotic treatments were applied in 5 levels (-2, -4, -6 and -8 bar for 72 hours and non-primed) by polyethylene glycol (peg) and salinity treatments in 8 levels (0, 40, 80, 120,...

The objective of this study was to evaluate the effect of priming treatments on the upper and lower thermal limits for germination of Urochloa brizantha cv. basilisk, and testing the hypothesis that pré-imbibition affect thermal parameters of the germination. Pre-imbibed seeds both in distilled water (0 MPa) and PEG 6000 solution (-0.5 MPa) were put to germinate in different temperatures. It is...

The early stages of quinoa germination are sensitive to drought stress. For this purpose, a study entitled the effect selenium in different concentrations on characteristics and some antioxidant enzymes under stress conditions with polyethylene glycol (PEG 6000) was investigated. first experimental factor seed priming (from two sources: sodium selenate nanoparticles: SeNPs ? 33.4 nm) at 0.5, 1....

The growth and performance of cowpea seedlings are negatively impacted by climate change the subsequent occurrence drought stress. Osmotic stress leads to formation reactive oxygen species, causing membrane breakdown, impairs metabolic activities. harmful effects osmotic can be reduced using seed priming techniques. Seeds var. Anaswara were treated with polyethylene glycol (PEG) ?-amino butyric...
