DOR: 98.1000/2383-1251.1397.5.147.9.1.1578.41 Extended abstract Introduction: Quinoa, with the scientific name (Chenopodium quinoa Willd), belongs to the Spencer family. Seeds vigor can be improved with a variety of seed priming methods. In this method, the seeds are soaked in water or various osmotic solutions and then dried to the original moisture. After priming treatment, seeds are stor...
in order to investigate the effect of different ratios of ammonium: nitrate on the photosynthesis and fatty acid composition in canola (brassica napus l.) under different levels of salinity, an experiment was conducted as a factorial based on complete randomize design at agricultural research center in east azerbaijan in 2010. the first factor was different ratios of nitrogen sources to ammoniu...
abstract nitrogen is a key nutrient in plant growth and it is necessary for amino acid synthesis. sulfur has very important role in the biosynthesis of the alliums flavor and pungency precursors and potassium improve crop yield and quality. in order to study the effect of ammonium nitrate and potassium sulfate on concentration some of the mineral elements in onion (allium cepa l. azar shahr cv....
in order to evaluate the effect of different mechanical treatments (application of sulphuric acid, boiling water and flooding) on seed dormancy breaking of licorice, an experiment was carried out in randomized complete block design in 2012. moreover, a factorial scheme in rcbd was performed to assess the application of giberalic acid and potassium nitrate treatment as well as stratification and...
The effect of different sources of nitrate salts (ammonium nitrate, sodium nitrate and potassium nitrate) on nitrate reductase (NR) activity and nitrate reductase expression in the leaves of Foeniculum vulgare seedlings grown in pots containing perlite. Two week old seedlings were treated with 30, 60 and 120 mM aqueous solution of ammonium nitrate, sodium nitrate or potassium nitrate. After 21 ...

Cucurbita pepo L. plants were grown in plastic pots with 2 kg washed sand per pot at three levels of potassium and sodium nitrate supplies to investigate the effects of nitrate supply on nitrate reductase activity and nitrate reductase expression in the leaves of the plants. Results demonstrated that starvation leads to decrease nitrate reductase activity and nitrate reductase expression. Suppl...
Reduction of nitrate takes place when the stored energy in the form of colour centres is released during dissolution of g-irradiated crystalline potassium fluoride in aqueous potassium nitrate solution. Various parameters like dose, amount and storage time of irradiated potassium fluoride which control the yield of nitrite have been studied. Similarly, the effect of concentration of potassium n...
background and aims . the aim of this study was to evaluate the clinical desensitizing effects of potassium nitrate and strontium acetate in reduction of hypersensitivity. materials and methods . thirty eight patients who presented dental hypersensitivity were selected and randomly allo-cated into two groups. group i: patients who were treated by potassium nitrate 5% foam, and group ii: patient...
this experiment was conducted to evaluate of different levels of water nitrate on performance and blood parameter of broiler chicks. 240 day old ross 308 were assigned in 5 treatments, 4 replicates and 12 chicks per replicate in a completely randomized design. treatments so that water nitrate concentration was 10 mg in drinking water of poultry farm (control group or cg) and another treatment 4...
