concinciding of wheat growth in post-anthesis period by water deficiency can result in reduction of current photosynthesis. in this circumstance stem-stored carbohydrate from pre-anthesis period had an important role in supporting assimilates for growing grain. an experiment was conducted in 2007-8 in experimental farm of arsanjan islamic azad university, in order to investigation the quantity ...

Inhaled nitric oxide (iNO) is commonly used in the treatment of very ill pre-term newborns. Previous studies showed that exogenous NO could affect endothelial NO synthase (eNOS) activity and expression in vascular endothelial cell cultures or adult rat models, but this has never been fully described in newborn rat lungs. We therefore aimed to assess the effects of iNO on eNOS expression and act...

Background: Plant growth regulators (PGRs) have important roles in many processes such as germination, seedling growth, nutrition uptake, morphogenesis, ripening, etc. Objective: This study aimed to evaluate the effect of gibberellic acid, indole butyric acid, and methanol as plant growth regulators on morpho-physiological and phytochemical features in Thymus vulgaris L. Methods: The farm...

Climate change effects on UK winter wheat grain yield are complex: warmer temperature, negative; greater carbon dioxide (CO 2 ) concentration, positive; but other environmental variables and their timing also affect yield. In the absence of long-term experiments where temperature CO concentration were manipulated separately, we applied crop simulation model Sirius with daily meteorological data...

Field studies were conducted to determine the potential for alterations in physiology and the intraspecific variation in sensitivity of 20 wheat (Triticum aestivum) cultivars to enhanced ultraviolet-B (UV-B, 280-315 nm) radiation. The supplemental UV-B radiation was 5 kJ m(-2), simulating a depletion of 20% stratospheric ozone. Out of 20 wheat cultivars (from South China, North China and Mexico...

A total of 400 barrows from Dekalb EB and 83 terminal sires mated to 43 and 45 maternal lines were used to evaluate the effects of dietary ractopamine (RAC; Paylean, Elanco Animal Health, Greenfield, IN) concentrations (0, 5, 10, or 20 ppm; as-fed basis) and feeding durations (6 to 34 d) on growth, efficiency, carcass, and meat quality characteristics of finishing pigs. Barrows were weighed and...

Some studies have suggested that the immunogenicity of oats depends on the cultivar. RP-HPLC has been proposed as a useful technique to select varieties of oats with reduced immunogenicity. The aim of this study was to identify both the avenin protein patterns associated with low gluten content and the available variability for the development of new non-toxic oat cultivars. The peaks of alcoho...
