 Mahisefid, Rutilus frisii kutum , is a cyprinid fish which is distributed from Turkmenistan to Azerbaijan along the Caspian Sea. It is one of the economically important fish in the region. As part of the Iranian Fisheries Company’s policy to improve the stocks of this species, every year, fingerling of Mahisefid are released into the southern basin of the Caspian Sea. The main objective of thi...

Background & Aims of the Study Irradiation with ultraviolet light (UV) is used for the disinfection of bacterial contaminants in the production of potable water. The main objective of the study was to investigate and model Disinfection By-Products (DBPs) formation due to the UV Irradiation of the Tajan River water under different Irradiation conditions. Materials & Methods: &nbs...

Most researches on wheat and barley breeding for salt tolerance have focused mainly on excluding Na+ from different tissues but the results of some experiments suggest that contribution of Na+ exclusion to salt tolerance is overshadowed by other physiological responses. Three bread wheat cultivars differing in salt tolerance (Arg, Tajan and Baharan) and one barley cultivar (Nik) were employed t...

This experiment was conducted to evaluate the effects of foliar application of ordinary and nano-particles of zinc and iron oxide on the responses of two wheat cultivars (kavir and Tajan) to three levels of salinity (0, 75 and 150 mmol kcal). The experiment was arranged as factorial in a randomized complete block design with four replications. Plant height, leaf area, shoot and root dry weight,...

Heavy metals tend to be adsorbed and accumulated in sediments as opposed to water or suspended solids. Sediments and biota bodis can act as a final sink for heavy metals in the aquatic environments. They accumulate through the food chain posing potential biological and ecological risks. Therefore, research on the heavy metal concentrations in aquatic ecosystems can help to protect human health ...

The present research was performed for studying morphological variation and investigating the presence of relationship between molecular markers related tillering in some genotypes of bread wheat under the field farm and laboratory conditions. In the field experiment, three seed densities including 150, 300 and 450 seed per square meter as the main plot factor and also 10 genotypes including th...

Basically, the most important limiting factor in plant growth is the lack of water. More lands in Iran are located in arid and semi-arid region and so identifying of ghenotype that can produce acceptable yield under drought conditions is essential. In order to identification of drought stress tolerant varieties, 20 wheat cultivars were evaluated at three stress levels (control, -0.6 and -1.2 MP...

Background: Iran is located in the global arid zone. With an average rainfall of less than 250 mm. 25 percent is Iran of located in hyper-dry area and 40 percent in the arid area. In 2007, the World Bank report declared the annual reduction of freshwater resources in Iran 6 times more than global standards and indicators. Since at present, in Iran most available fresh water enters the water eco...
