background and objectives: one of the most important limiting factors of crop growth in the arid and semi-arid regions, is water deficit stress. mycorrhizal fungi are one of the most important microorganisms in the rhizosphere. the effects of these fungi apply via changes on some of the characteristics of roots and nutrient uptake in host plants in drought conditions. however, symbiotic mycorrh...

Objective of this study was to evaluation Changes in proline, catalase and germination characteristics of barley seeds under salinity stress. Salinity stress at osmotic potentials of 0 (as control), 4, -8, -12 and -16 bar were adjusted using NaCl before the start of the experiment. Our results showed that, the effect of salinity levels for all traits was significantly. With, increases of salini...

in a pot experiment the effect of water stress on the proteins and proline amino acid content of jam, kurosh, pirooz chickpea cultivars (cicer arientinum) were evaluated using a complete block design with factorial treatments inducing cultivars and watering periods, three, six and nine day intervals in three replications. soluble protein and free proline content of the leaf and the root were me...

This study was carried out to appraise whether or not the exogenous application of a potential osmoprotectant, proline, could ameliorate the adverse effects of drought stress on maize seed and seed oil composition, as well as oil antioxidant activity. Water stress reduced the kernel sugar, oil, protein and moisture contents and most of the seed macro- and micro-elements analyzed in both maize c...

two field experiments were conducted at the research farm of the faculty of agriculture, university of tabriz, iran during 2009-2010 and 2010-2011, to evaluate the response of fennel (foeniculum vulgare l.) landraces to limited irrigation. experiments were arranged as split plot based on randomized complete block design in three replications with irrigation treatments (irrigation after 60, 90, ...

Saline soils and saline irrigation waters present poten­tial hazards to canola production. Therefore, in this study in order to find indicators for salt tolerance, the changes of proline content and the activities of antioxidant enzymes were investigated in two canola genotypes (H308, H420) under various salt concentrations (0, 50, 100, 150 and 200 mM). Results showed that compared to the contr...

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...
