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...
Effect of various NaCl treatments (0, 50, 100, 200, and 300 mM) at different growth and development stages (tillering, boot swellen, flowering and anthesis) in two wheat cultivars (Ghods: salt – sensitive, Boolani: salt – resistant) on SDS-PAGE electrophoretic pattern of leaf proteins was studied under greenhouse conditions. Generally, in response to salinity treatments, the decrease in protein...
The aim of this study was to evaluate physiological responses and elemental composition three salt tolerant alfalfa (Medicagosativa L.) cultivars, ‘Halo’, ‘Bridgeview’, ‘Rugged’, two intolerant cultivars ‘Rangelander’ ‘Vernal’ under five salinity levels (0 dSm−1, 4 8 12 dSm−1 16 dSm−1) in a sand based hydroponic system the greenhouse. germination percentage among highest for ‘Halo’ stress. ‘Rug...
Photosynthesis and wheat grain yield responses to supplemental irrigation with different amount of applied water under dryland conditions were investigated. Therefore, a two-year field experiment was conducted research farm of College of Agriculture, Shiraz University during 2004-2005. Five levels of irrigation including dryland conditions, irrigation at stem elongation, booting, flowering an...

Salinity is a limiting factor in agricultural production that inflicts great damages on agricultural products. In order to decrease or stop salinity stress, numerous methods are proposed by different researchers. One of the methods to reduce the damages of salinity stress is cultivating tolerant plants to salinity. In this research, resistance of three radish cultivars to salinity stress was in...
the present study aimed at investigating how different news agencies using the concept of legitimation/delegitimation represent the same event differently. to this end, van leeuwens (2008) legitimatory/delegitimatory framework was applied to the data gleaned from the iranian state-run news agency fars news, british state-run news agency bbc, and also american state-run news agency voa. the resu...
In order to study the effect of different levels of salinity and nitrogen (N) on physiological and biochemical reactions of two wheat genotypes at anthesis stage, a factorial experiment was performed as completely randomized design with three replications, in Research Greenhouse of Agricultural, Medical and Industrial Research School of Karaj‎‎ in 2011.‎ Treatments were two wheat cu...
A field experiment was conducted to determine the sensitivity of wheat to water stress and changes in water relations and yield of wheat (Triticum aestivum L.) under water stress conditions applied at different growth stages. The experiment comprised of two wheat cultivars and four water stress treatments, maintained by withholding water at tillering, anthesis, and at both stages. Water stress ...
Although inter-variety variability for salt tolerance has been reported in bread wheat plants, little information is available on the genetic control of ion contents and biomass yield under saline conditions. A diallel cross, including reciprocals of two salt tolerant, two moderately tolerant and two sensitive Iranian and exotic bread wheat varieties, was analyzed to investigate the inheritance...
