This study was conducted to evaluate changes in antioxidants, free proline, relative water content and determination of root colonization of four commercial wheat (Triticum aestivum L.) cultivars (Azar2, Darab2, Shiraz, and Falat) inoculated with the fungus Glomus intraradices, under four water regimes of 100, 75, 50, and 25% of field capacity in the year 2010 at the School of Agriculture, Shir...

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 ...

Water can be a major component of aerosol particles, also serving as a medium for aqueous-phase reactions. In this study, a novel method is presented to calculate the aerosol liquid water content at high relative humidity based on measurements of aerosol hygroscopic growth factor, particle number size distribution and relative humidity in the Haze in China (HaChi) summer field campaign (July–Au...

The phospholipid headgroup composition and fatty acid composition of a gram-positive halotolerant Planococcus sp. (strain A4a) were examined as a function of growth temperature (5 to 35 degrees C) and NaCl content (0 to 1.5 M) of the growth medium. When the growth temperature was decreased, the relative amount of mono-unsaturated branched-chain fatty acids increased. When Planococcus sp. strain...

Drought stress is one of the most important factors limiting the survival and growth of plants in the different habitats of Iran. Detailed knowledge about the ecophysiological responses of native plants to drought stress could contribute to the success of breeding and re-vegetation programs. Six wild populations of Anthemis tinctoria, were assigned to four drought treatments, i.e. well...

The aim of this experiment was to determine the response of dill (Anethum graveolens L.) towater deficiency and salinity. In spring, dill biomass decreased with increasing water deficiencydue to a reduction in the number and mean weight of leaves per plant. The concentrations ofchlorophyll, carotenoids, vitamin C and total phenolics within the leaves were unaffected bywater stress, but the Cl, ...

Abiotic stresses including salinity are the major limiting factors of growth and crop production worldwide. Microbial endophytes as the most important soil microorganisms, by modifying plants at genetical, physiological and ecological levels increase their yield per area unit and provide the possibility of crop production in saline and arid soils or climates with biotic and abiotic stresses. Th...
