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 plays an important role in the reduction of tomato growth, especially in arid and semi-arid regions. Nitrogen (N) may increase tomato tolerance to salt stress by increasing plant growth. In order to investigate the interaction effect of salinity and nitrogen on tomato growth, fruit quality, and micronutrient concentration in tomato plants, a hydroponic experiment was conducted in a com...

this study was conducted to find out the influence of in vitro salinity on growth parameters shoot length, number of leaves, number of new buds, the chlorophyll, chlorosis and necrosis and absorption of sodium, chloride, potassium, nitrogen and phosphorus of pear (pyrus communis cv. dargazi) in vitro propagated shoots. the experiment was conducted as a complete randomized design with 5 salinity...

Soil water, salinity and nitrogen content are three major factors affecting crop production in arid and semi-arid areas. This study was performed in two years of 2009 and 2010 in a semi-arid area in order to investigate the effects of irrigation water quantity (as main plot), quality (saline water, as sub-plot), nitrogen fertilizer (as sub-sub plot) and their interactions on growth and yiel...

introduction soil salinity is a major limiting factor in agricultural development within iran. nitrogen is the most important nutrient that its uptake is limited over other elements under saline conditions due to decrease in the permeability of plant roots, soil microbial activity and mineralization of organic compounds and nitrate uptake by high concentrations of chloride anions in the root zo...

Environmental stresses, such as shading of the shoot, drought, and soil salinity, threaten plant growth, yield, and survival. Plants can alleviate the impact of these stresses through various modes of phenotypic plasticity, such as shade avoidance and halotropism. Here, we review the current state of knowledge regarding the mechanisms that control plant developmental responses to shade, salt, a...

effects of salinity and drought on growth, contents of proline, malondialdehyde (mda), proteinand activity of antioxidative enzymes were studied in two trigonella species. seeds andexplants of t. foenum-graecum and t. aphanoneura were grown on murashige and skoogmedium (ms) complemented with iso-osmotic concentrations of nacl (0, 100, 150 mm) andmannitol (0, 180, 275 mm). growth and relative wa...

Abiotic stresses, including drought, salinity, heat, and cold, negatively affect maize (Zea mays L.) development and productivity. To elucidate the molecular mechanisms of resistance to abiotic stresses in maize, RNA-seq was used for global transcriptome profiling of B73 seedling leaves exposed to drought, salinity, heat, and cold stress. A total of 5,330 differentially expressed genes (DEGs) w...
