Salinity is one of major stresses which can severely limit plant production, especially in the arid and semi-arid regions. The present study was carried out to evaluate the impact of salinity stress on some physio-biochemical parameters in nitre bush plants (Nitraria schoberi). Thus, an experiment was carried out under natural conditions and salinity stress was induced by a combination of diffe...
drought and salinity are two important environmental stresses limiting the crop production. in order to study the influence of drought and salinity stresses on germination characteristics of marshmallow plant seeds, two separate experiments were conducted based on completely randomized design with four replications in controlled conditions. drought stress levels were 0, -2, -4, -6 and -8 bar in...
Soil salinity is a serious environmental problem that has negative impacts on growth and production of plants. On the other hand, application of chitosan has recently been increased to enhance the resistance to different stresses, such as salinity. In order to study the effect of chitosan seed-priming on alleviation of salinity stress in fenugreek (Trigonella foenum-graecum L.) a factorial expe...
High-salinity stress considerably affects plant growth and crop yield. Thus, developing techniques to enhance high-salinity stress tolerance in plants is important. In this study, we revealed that ethanol enhances high-salinity stress tolerance in Arabidopsis thaliana and rice. To elucidate the molecular mechanism underlying the ethanol-induced tolerance, we performed microarray analyses using ...
salinity is a phenomenon that does not satisfy the crop water requirement and leads reduction vegetation. to control of this phenomenon requires appropriate management and monitoring of spatial and temporal salinity variations from the past to the present in this study the spatial and temporal changes of soil salinity of irrigation and drainage network located in garmsar, iran, is investigated ...
A field experiment was carried out to study the response of presoaked faba bean seeds (Vicia faba cv. Misr 2) in freshly prepared ascorbic acid (50 ppm) or distilled water (control) for 4 hrs at natural environmental conditions, to salinity stress. NaCl treatments caused a reduction in all productivity and yield parameters as compared with control, particularly at high NaCl level (150 mM), wher...
The effects of shading in combination with salinity treatments were studied in citrus trees on two rootstocks with contrasting salt tolerance to determine if shading could reduce the negative effects of salinity stress. Well-nourished 2-year-old 'Valencia' orange trees grafted on Cleopatra mandarin (Cleo, relatively salt tolerant) or Carrizo citrange (Carr, relatively salt sensitive), were grow...
Chickpea (Cicer arietinum L.) is highly sensitive to salinity and selection of chickpea genotypes that are moderately tolerant to salinity can help to expand chickpea cultivation in saline areas. Eleven chickpea genotypes were grown in a hydroponic system containing different NaCl concentrations (8 and 12 dS m-1) and control (Hoagland solution) in order to study the effects of salt stress on ph...
three medium magnitude events happened inside the transitional border of south alborz and central iran; namely kahak-qom 2007/06/18 event with ml 5.6, zanjan 2008/05/27 event with ml 5.3 and aradan-garmsar 2007/11/19 event with ml 5.1. this provides us the opportunity to compute focal mechanism and stress drop of the events and compare them with those events happened within the alborz range.
salinity is one of the important factors that reduce the growth and yield of crops in iran; however, determining appropriate methods for reducing its negative effects is important. in order to study the effects of nutritional condition of mother plant and bacterial biofertilizers seed priming on germination indices of wheat (triticum aestivum l.), in salinity condition, an experiment was conduc...
