to study the effect of salinity stress on some physiological attributes of four grape cultivars in vineyards of urmia in iran, an experiment was carried out as factorial arrangement in randomized complete block design with four replications. experimental factors included: grape cultivars qazel ozum, qareh shireh, tabrzeh and dizmari, and salt concentrations 0, 25, 50 and 100 mmol l-1 and locati...
paclobutrazol was utilized to analyze its role in water stress amelioration and post drought recovery of container-grown pear ( pyrus communis cv. biroti ) saplings. following planting, paclobutrazol was applied as soil drench at concentration of 0, 0.15 and 0.3 mg per pot. three months following planting, saplings were subjected to three water stress treatments of: 0, -0.4 and -0.8 mpa. contro...
abstract part one: the electrode oxidation potentials of a series of eighteen n-hydroxy compounds in aqueous solution were calculated based on a proper thermodynamic cycle. the dft method at the level of b3lyp-6-31g(d,p) was used to calculate the gas-phase free energy differences ,and the polarizable continuum model (pcm) was applied to describe the solvent and its interaction with n-hydroxy ...
to study some physiological and morphological traits of sugar beet varieties in response to salinity stress, three multi-germ sugar beets (13030, 22393 and ic) were grown in the greenhouse, faculty of agriculture, shahid chamran university, in 2009. the experiment was carried out under three levels of salinity in from of sodium chloride source, that included control (zero), 100 and 200 mm uses ...
a greengouse experiment was conducted to evaluation of salinity stress on growth parameters of two olive cultivars during 2013-2014 at agricultural and natural resources research center of tehran. in the experiment, effects of five levels of irrigation water salinity including 0, 4, 8, 12 and 16 ds.m-1 were evaluated on ʻzardʼ and ʻmissionʼ olive cultivars under soilless culture. data showed th...
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
The influence of Nitrogen (N) rates on mineral nutrient uptake in stem and seeds, proline and carbohydrate in flag leaves of Wheat (Triticum aestivum L . Var Chamran) under saline conditions was studied in a field experiment in 2003 and 2004. The experiment was conducted using a split plot design with three replications. The treatments comprised five levels of salinity: 1.5, 5, 10, 15 and 20 ds...
soil compaction has become a widespread problem in the world and it is considered as one of the main factors affecting land degradation in arid and semi-arid agricultural land. the aim of this study was to investigate the effects of soil compaction on soil carbon and nitrogen sequestration, physical (aggregate stability, saturated soil moisture content, bulk density, and porosity) and chemical ...
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 ...
abstract this study aimed at investigating the impact of etymology strategy instruction on the development of vocabulary of iranian intermediate efl learners. etymology, knowledge of origin of words, roots, and affixes, has proved to be a controversial issue and a question of long debate with regard to its impact on the process of vocabulary learning. this study employed etymology strategy in ...
