Salinity is one of the most serious factors limiting the productivity of agricultural crops, with adverse effects on germination, plant vigour and crop yield (R Munns & Tester, 2008). Salinization affects many irrigated areas mainly due to the use of brackish water. Worldwide, more than 45 million hectares of irrigated land have been damaged by salt, and 1.5 million hectares are taken out of pr...

Triticum aestivum L. and Zea maize L. are both sensitive to salinity stress which is a major problem faced by farmers today. In the present study, the effect of chitosan, a biologic elicitor under salinity stress was examined on growth parameters and biochemical markers in maize and wheat s...

Challenged by the low salinity, 4 parts per thousand (4 ppt), for 72h, the survivals of swimming crabs (Portunus trituberculatus) were collected as the screened group (SG, tolerant to low salinity). Aiming at identifying the mechanism of low salinity tolerance, quantitative real-time PCR was employed to investigate the expression profiles of 4 HSP genes (HSP60, HSP70, HSP90-1, HSP90-2) in the h...

in order to evaluate the effects of drought and salinity stresses on growth parameters and essential oil of lemon balm, two experiments with three replications in a randomized complete block design were applied. five levels of salinity including zero, one, two, three and four ds/m of sodium chloride solution, and five drought stress treatments including 50, 62.5, 75, 87.5 and 100% as available ...

Salinity is one of the major factors which reduces crop production worldwide. Plant responses to salinity are highly complex and involve a plethora of genes. Due to its multigenicity, it has been difficult to attain a complete understanding of how plants respond to salinity. Genomics has progressed tremendously over the past decade and has played a crucial role towards providing necessary knowl...

Salinity is one of the severe problems in worldwide agricultural production. Soil salinity limits the productions of both forage and grain legumes. Adverse effects of salinity are mediated through detrimental effects on the rhizobium legume interactions that lead to the establishment of the nitrogen fixing symbiosis. Salt stress inhibits the initial steps of the rhizobia legume symbiosis. For i...

     Salinity stress is one of the most important abiotic stresses that effects on many agronomic, nutritional, physiological and biochemical processes of crops. A factorial experiment based on completely randomize design with four replications under laboratory conditions with four maize hybrids (SC640, SC704, SC740 and SC Simon) and three levels of salt stress (0, 100 and 200 mM NaCl) was carr...

Salinity is one of the main obstacles to the successful production of agricultural products. Hormonal compounds such as salicylic acid (SA) as plant growth regulators can have different physiological and biochemical effects in plants under salt stress. In present research, the effects of different concentrations of sodium chloride (2, 6 and 10 dS/m) and foliar application of SA (0, 0.25 and ...

Salinity stress affects morpho-physiological and biochemical traits of plants. The transgenic Bt plants play a significant role in pest control, but their response and ability to cope with environmental stresses still need to be evaluated. Therefore, effect of salinity stress at 0, 50, 100, 150, and 200 mM on morphological, physiological, and molecular traits of T3 transgenic tomato plants cont...

Soil salinity is one of the most severe factors limiting nodulation, yield and physiological response in soybean. The possible role of plant growth promoting rhizobacteria (PGPR) in restricting mineral nutrients and thus alleviating soil salinity stress during plant growth has not yet been established. In this study, the beneficial effects of inoculation with salt-stressed PGPR strains were inv...
