An experiment was conducted to investigate the effects of zinc application and salinity stress (0, 33, 66 and 99 mM NaCl) on some morphological and physiological parameters of soybean (Glycine max L., var. Williams). Results showed that zinc application improved shoot length, root fresh and dry weight and shoot fresh and dry weight under all salinity treatments. The catalase (CAT), ascorbate pe...

to find out the effect of sodium nitroprusside (snp) in reducing oxidative damage induced by salinity stress in barley seedlings, a crd based factorial experiment with three replications was conducted in agronomy laboratory of the faculty of agricultural sciences, university of guilan, in 2012. the experimental design consisted of two snp levels (0.1 and 0.2 mm snp; as nitric oxide (no) donor) ...

Despite the large interest in the use of Chenopodium quinoa as a crop on extreme habitats, very little is known about growth response and seed yield under saline conditions. As a prerequisite for its sustainable utilization in salt-affected areas, this study aimed to unravel individual physiological and morphological mechanisms that determine its salt tolerance. Hence, the plants were grown in ...

in this study the effect of salt stress on banding patterns of superoxide dismutase (sod), catalase (cat) and peroxidase (pox) in 18 genotypes of white common bean (phaseolus vulgaris l.) were examined under two levels of nacl )0 and 400 mm) stress. for each isozymic band the “density × area” scores on gels were evaluated by mcid software and considered as enzymatic activity. three isozymes wer...

Puccinellia tenuiflora is a typical salt-excluding halophytic grass with excellent salt tolerance. Plasma membrane Na+/H+ transporter SOS1, HKT-type protein and tonoplast Na+/H+ antiporter NHX1 are key Na+ transporters involved in plant salt tolerance. Based on our previous research, we had proposed a function model for these transporters in Na+ homeostasis according to the expression of PtSOS1...

The objective of the study was to investigate effects salinity stresses (50, 100, 150, 200 and 250 mM NaCl) on germination early seedling growth six cotton varieties (Lydia, Carisma, Flash, BA151, BA525 ST468) under optimum (25°C) low temperature (18°C) conditions. Germination percentage, mean time, index, stress tolerance length, vigor fresh dry weight were investigated. Results showed that le...

plant growth is often limited by low levels of soil micronutrients such as copper (cu), ‎especially in calcareous salt-affected soils of arid and semiarid regions. the aim of this ‎work was to investigate individual and combined effects of salinity and cu on growth, leaf ‎relative water content (lrwc), cell membrane permeability, lipid peroxidation, and total ‎phenolic content (tpc) of rosemary...

Late embryogenesis abundant (LEA) proteins are involved in tolerance to drought, cold and high salinity in many different organisms. In this report, a LEA protein producing full-length gene OsLEA3-2 was identified in rice (Oryza sativa) using the Rapid Amplification of cDNA Ends (RACE) method. OsLEA3-2 was found to be only expressed in the embryo and can be induced by abiotic stresses. The codi...
