in order to evaluate the effects of drought stress and spraying of salysilic acid and chitosan on photosynthetic pigments and antioxidant enzymes of safflower an experiement was conducted as split plot randomized complete block design at the zabol university research farm in zabol, south iran during 2012. treatments were drought stress at three levels; irrigation when the soil moisture level dr...

recently, application of sa has increased to improve plants resistance to stresses such as drought. hence, to investigate sa effects on morphophysiological characteristics of fennel(foeniculum vulgare mill.) under drought stress, a split plot experiment based on latin square design with three replications was carried out at research farm of shahid bahonar university of kerman in 2012. three lev...

drought and salinity stress are adverse environmental factors that affect crop growth and yield. abiotic stress cause some reaction in plants such as change in gene expression, cell metabolism, growth and yield. moreover, stress condition resulted in increase of reactive oxygen species and disturbe macromolecules such as proteins, fatty acids, nucleic acid and pigments. in order to evaluate sal...

In the present study, effects of NaCl concentrations (0, 20, 40 and 80 mM) were investigated in Ceratophyllum demersum. Macronutrients N, P and K and micronutrients Zn and Cu were significantly decreased by NaCl salinity. In general, however, Fe and Mn accumulation showed to increase. As a results, NaCl toxicity disturbed the uptake and translocation of macro and micronutrients in the macrophyt...

Bone marrow stromal stem cells (BMSCs) play a significant role in cell therapy. These cells quickly die after transplantation to the affected area due to oxidative stress. The natural disaccharide, trehalose which can be known as autophagy inducer. The present study aimed to investigate the role of trehalose in preventing BMSCs from oxidative stress caused by H2O2. BMSCs were isolated from the ...

Objective(s):Hyperglycemia mediated oxidative stress plays a key role in the pathogenesis of diabetic complications like nephropathy. In the present study, we evaluated the effect of ethanolic extract of Ensete superbum seeds (ESSE) on renal dysfunction and oxidative stress in streptozotocin-induced diabetic rats. Materials and Methods:Glucose, HbA1c, total protein, albumin, renal function mar...

drought is the most common environmental stress in vineyard occurs in soils with low water content, even in irrigation condition. to evaluate foliar spraying of ascorbic acid under drought stress, a research during 2012 to 2013 years in the natural environment, and one year after the establishment of the cuttings in clay loam soil was conducted. cultivars with two-level white seedless and khosh...
