high temperature, high radiance, low vapor pressure, and lack of precipitation in most months characterize arid ecosystems. under these conditions, tree crops such as pistachio suffer from drought combined with salinity stress. in order to investigation effects of combined salinity and drought stress on function of photosynthetic apparatus, mutica pistachio (pistacia mutica) seedlings were subj...

Osmotic stress is the most important of the abiotic stresses that lead to limitation of growth and yield in rapeseed. This study was conducted to examine the effect of cycocel seed priming on osmotic stress tolerance in germination and early growth stages of rapeseed, as a factorial experiment based on completely randomized design at Agriculture College of Shiraz University in 2012. The treatme...

Dianthus barbatus is an important ornamental bedding plant in temperate regions with traditional medicinal applications. Water shortage and drought stress are major limitations for landscape development and plant medicine production. Callogenesis is the key step for modern plant breeding techniques and in vitro drought stress study defines the mechanisms of plant response to stress. Therefore t...

Drought stress influences seed germination and seedling growth of many plants. Seed coating is technique of covering seeds with adhesive agents to improve seed performance and plant establishment and could be used to alleviate the negative effects of osmotic stress. In order to solve the problem of low germination and poor vigor of sweet corn under osmotic stress conditions (0, -0.3, -0.6 and -...

This research was performed in 2011 at University of Mohaghegh Ardabili, Iran, to evaluate osmotic-stress tolerance, at seedling stage, of rapeseed (Brassica napus L.), as a split plot experiment based on randomized complete blocks design with four replications. Levels of osmotic stress were considered as main factor and twelve rapeseed cultivars were sub-factor, that were evaluated under aquac...

Background: Sunflower (Helianthus annuus L.) is one of the important vegetable oil supplies in the world and in Iran, as well. It is classified as a drought semi-tolerant crop; however, its yield is adversely affected by drought stress. Understanding the initial events in sensing stress and the related physiologic and biochemical events thereafter, is crucial in designing droug...

Gastrointestinal epithelium faces osmotic stress, both at physiological and pathophysiological conditions. JNK activation is an immediate cellular response to osmotic stress. We investigated the effect of osmotic stress on intestinal epithelial barrier function and delineated the role of JNK2 in osmotic stress-induced tight junction (TJ) regulation in Caco-2 cell monolayers and ileum of Jnk(-/-...

drought is one of the most important abiotic stresses affecting plant growth and development. in the present study, the changes in lipid peroxidation rate and antioxidant enzyme activities were determined at different concentrations of polyethylene glycol (peg) 6000 (0, 5, 10, and 15% (w/v)) for two canola cultivars (slm046 and hyola 308). in order to produce water deficit, 12 days old canola s...

This study was conducted to evaluate the effect of osmotic stress on physiological characters of wheat cultivars as a factorial experiment based on completely randomized design with three replications in 2012 at the Mohaghegh Ardabili University. Twenty wheat cultivars studied in three stress levels (control, -6 and -12 Bars). Analysis of variance showed that the stress had significant effect o...

environmental stresses such as drought have important effects on plant growth and development. in order to evaluate the effect of drought tolerance, 12 chickpea genotypes were treated with drought stress in hydroponic condition in greenhouses. treatments were a control and two stress treatments -3 and -6 bar that was created with polyethylene glycol in hydroponic condition. two weeks after the ...
