the present study was laid out in order toevaluate the effect of salinity on some biochemical characterize of grapevine c.vyaghouti. the experiment was done at agricultural and natural resources research center, ilam, iran at 2014. the experiment was a completely block design (crd) with four replications. saline factor was nacl salinity in seven levels (zero, 50, 100, 150, 200 and 250 mm). grap...

in order to evaluate the effect of different levels of salinity and three nitrogen nutrition on biochemical reactions and changes in dry weight of shoot and root on psyllium (plantago ovata f.), a glasshouse experiment in a complete randomized design with three replications in 2009 at university of zabol was conducted. salinity treatments in this experiment were 0, 100 and 200 mm of nacl and ni...

background: an essential oil is a liquid that is generally distilled from the leaves, stems, flowers or other elements of a plant. objective: cumin (cuminum cyminum l.) essential oil (ceo) was analyzed to determine oil component. antifungal effect of ceo was determined by in vitro technique. in second stage, effect of different concentrations of ceo by pdm on postharvest life of strawberry (fra...

iran is the center of origin as well as variation for pomegranate (punica granatum l.). also, iran is one of the most important countries in the world in terms of pomegranate culture and production. monitoring morphological and physiological changes which occur during fruit growth and development is an important determining in orchard management decisions. the aim of the present research was to...

The results of experiments on municipal wastewater primary effluent are presented for a pilot-scale submerged membrane bioreactor (SMBR). The SMBR pilot plant employed an ultrafiltration membrane with a nominal pore size of 0.035 microm and was operated at a constant membrane flux of 30 L/m(2)h. The mixed liquor suspended solids (MLSS) concentration was maintained at 8+/-2 g/L and steady-state ...

Water-soluble hydrophobically associating polymers are examined with particular emphasis on their rheology for oilfield applications. The incorporation of a small amount (less than 1 mol%) of hydrophobic groups into the polymer backbone of a water-soluble polymer dramatically alters the rheological properties of the resulting material. Associating polymers have potential for use in mobility con...

A lab-scale SBR equipped with a flat sheet membrane in submerged configuration that is named MSBR was used for the treatment of composting leachate. It was fed by biologically treated leachate with overall 70-1360 mg/L Chemical Oxygen Demand (COD). The values of pH, Electrical Conductivity (EC), and Dissolved Oxygen (DO) were monitored r...

in order to evaluate the effects of atmospheric co2 concentration increment on rapeseed salinity tolerance, four levels of salinity(0, 5, 10 and 15 ds.m-1) on  three cultivars of rapeseed (okapi, zarfam, and rgs) at three levels of atmospheric co2 concentration(350, 700 and 1050 ppm) were studied. the experiment was conducted at the greenhouse of tarbiat modares university at 2010 and 2011 crop...
