in order to determine yield and physiological response of different wheat genotypes to low temperature, many pot and field experiments were conducted in 2007-2008 at the plant physiology laboratory, university of kurdistan, and ghamlo dryland agricultural research station in kurdistan province. in both experiments, the experimental design was a randomized complete block in a split plot arrangem...

effective microorganisms (em) is a commercial biofertilizer mainly consists of photosynthetic and lactic acid bacteria, yeast and actinomycetes. in order to evaluate the influence of em (0 and %1) and salt stress (0 mm, 50 mm, 100 mm and 150 mm) on the morphophysiological characteristics of pomegranate cv. shishe-kap, a factorial experiment was conducted based on the completely randomized desig...

Transgenic alfalfa (Medicago sativa) expressing Mn-superoxide dismutase cDNA tended to have reduced injury from water-deficit stress as determined by chlorophyll fluorescence, electrolyte leakage, and regrowth from crowns. A 3-year field trial indicated that yield and survival of transgenic plants were significantly improved, supporting the hypothesis that tolerance of oxidative stress is impor...

Glycoprotein nonspecific elicitor (NSE) and a specific elicitor preparation from intercellular fluids (SE) of tomato (Lycopersicon esculentum Mill. cv Bonny Best or Potentate) infected with race 2.4.5 of Cladosporium fulvum Cooke [syn. Fulvia fulva (Cooke) Ciferri] were injected into cv Sonatine (resistant to race 2.4.5) to compare electrolyte leakage, lipoxygenase activity, and lipid peroxidat...

The consistent correlation between desiccation tolerance in orthodox seed tissue and an accumulation ot certain "late embryogenesis abundant"" (LEAI proteins suggests that these profeins reduce desiccation-induced cellular damage. The aim of the present work was to test this hypothesis. Exogenous abscisic acid {ABAi was used lo elevate the level of heat-soluble LE.A-like proteins in axes from i...

Few studies have investigated the alkali-based salt resistance aspect of plants. Here, we used 2 pumpkin cultivars (‘Cucurbita ficifolia Bouch.’ and ‘Chuandilong’) to study the growth and physiological response mechanisms of pumpkin to different levels of NaHCO3 stress. After second true leaf development, pumpkin seedlings were treated with varying levels of NaHCO3 stress (0, 30, 60 and 90 mmol...

Fresh-cut leafy vegetables have been gaining importance in the human diet both for their nutraceutical proprieties and low calories content. The preparation procedures for fresh-cut production and the storage system may lead to severe leaf damages that may affect leaf colour and induce shortened shelf life. The aim of this work was to study the leaf pigment changes in cut and whole Swiss chard ...
