This research were carried out to evaluate physiological responses of wheat cultivars to salt stress using a factorial experiment cultivars (Chamran, Karchia66, Ghods, Tjan, Atrak, Roshan, Kavir, Mahoti, Alvand, Mahdavi, Niknejad, Biston, Sardari, Felat, Tabasi, Sorkhtokhm, Golestan, Darab2, Azadi) at seedling growth stage in two salinity levels (0 as control and 10 ds m-2 NaCl solution) in Isl...

A breeding hexaploid salt tolerant wheat line (MS-81-14) was produced from crossing of an Iranian salt tolerant wheat line (1-66-22) with Inia cultivar (from CIMMYT) at Karaj Research Station in 1991-92 cropping season. The F1 plants were grown at Karaj in 1992-93 cropping season, furthermore F2-F6 populations were evaluated under salinity stress conditions (EcSoil&Water = 8-12 ds/m) in Isfah...

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Soil salinity is one of the most critical factors reducing crop yield. SOS signaling is one of the significant pathways that regulate ion homeostasis and it has the important role in mechanism of plant resistance to environmental stresses such as salt stress. Roots are the first organ of plants exposed to salt, so the role of genes involved in this pathway and their relation to salt tolerance w...

in this thesis, a new optically active poly(amide-imide) (pai) was synthesized by the indirect polycondensation reaction of the l-phenylalanine based diacid chloride and 4,4?-diaminodiphenylether in the presence of triethylamine in n-methyl-2-pyrrolidone. the formation of pai was confirmed by ftir, 1h nmr and elemental analysis. in next step, the surface of titanium dioxide (tio2) nanoparticles...
