iv abstract this study examined the linguistic behaviors of two iranian efl teachers each of them teaching learners of two similar proficiency levels, a beginner level and an intermediate level, to investigate the relationship between the learners proficiency levels and the amounts and purposes for l1 use by the two teachers. the study was carried out to investigate whether there were differe...
In order to evaluate morphological and physiological responses of sorghum (Pegah cultivar) to salt stress (0, 5, 10 and 15 dS/m) and different salicylic acid (SA) levels (0, 0.75 and 1.5 mM), an experiment was carried out in research green house of college of Agriculture Shiraz University during 2012 using a factorial as randomized complete block design with four replications. The results ...
Sorghum is among the most important forages used in arid and semi-arid regions of south-eastern Iran. Application of some materials such as super absorbent polymer (SAP) in soil can increase soil water storage capacity and increase water use efficiency. The aim of the study was to estimate the relative membrane permeability of sorghum under irrigation regimes and superabsorbent polymer applicat...
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...
Salinity is one of the most important non- biological stresses which limit the production of agricultural yields in dry and semi arid regions. Humic acid as an organic acid and ascorbate as a powerful antioxidant can improve yield of plants under salt stress. In order to investigation effects of salinity and its interaction with ascorbate and humic acid on growth, photosynthetic pigments conten...
The aim of this study was to characterize the effect of decreased 2-cysteine peroxiredoxin (2-CP) on the leaf anti-oxidative system in Arabidopsis. At three stages of leaf development, two lines of transgenic Arabidopsis mutants with decreased contents of chloroplast 2-CP were compared with wild type and a control line transformed with an empty vector. Glutathione contents and redox state were ...
Aluminum toxicity is one of the most deleterious factors for plant growth in acidic soils because over 50% of the world’s potentially arable lands are acidic. In recent years, considerable research has been conducted to understand the mechanisms of Al toxicity and tolerance in plants. This paper reviews the effects of different concentration of Al on plant shoot, root physiological parameters s...
in recent years many researchers have been focused on interaction of small molecules with dna. dna is generally the primary intracellular of anticancer drugs, so the interaction between small molecules and dna can cause dna damage in cancer cells, blocking the division of cancer cells and resulting in cell death. the flavonoids are a large group of polyphenolic natural products that are widely ...
To elucidate how physiological and biochemical mechanisms of chilling stress are regulated by abscisic acid (ABA) pretreatment, pepper variety (cv. 'P70') seedlings were pretreated with 0.57 mM ABA for 72 h and then subjected to chilling stress at 10°/6°C (day/night). Chilling stress caused severe necrotic lesions on the leaves and increased malondialdehyde and H(2)O(2) levels. Activities of mo...
