laboratory studies were conducted to examine the effects of different concentrations of wild barley (hordeum spontaneum koch.) shoot and seed extracts on germination and seedling growth of wheat (triticum aestivum l.) and wild barley. in this study, all wild barley shoot extract concentrations (with exception of lowest concentration) significantly reduced wheat seed germination after 7 days. sh...

Wheat (Triticum aestivum) growth and yield are depressed by physical and chemical interference of weeds. Recently, wild barley (Hordeum spontaneum) population has increased in wheat fields of many provinces of Iran. Since, little is known about the allelopathic effects of wild barley residues in soil, greenhouse studies were conducted to examine the effects of soil amended residues of wild barl...

The Caspian Sea and its basin (e.g. Anzali wetland) is one of the natural habitats of wild common carp Cyprinus carpio. In this study the genetic structure of this species. In the south-west of Caspian Sea (the Anzali wetland) was investigated using PCR-RFLP analysis of D-loop region. Two hundred of mature fish were collected from 5 stations (40 individuals from each station) including Siahkesh...

for determination of economic damage threshold of four wheat (triticum aestivum l.) cultivars in different densities of wild mustard (sinapis arvensis l.), experiments were conducted at agricultural research station gorgan during 2010-2012. the experimental design consisted of four randomized complete blocks in a factorial arrangement. the treatments comprised of factorial combination of wild m...

in order to study the complementary effects of application time of two herbicides sulfosulfuron 75% wg (apyrus) and 75% sulfosulfuron + 5% metsulfuron-methyl (total) and planting wheat density on wild barley (hordeum spontaneum koch.) control, an experiment was conducted in randomized complete blocks design with two-factors during 2012-2013 growing season in zarghan (fars). the first factor was...

Wild goat (Capra aegagrus) is one of the most prominent mountain mammals dispersed in many habitats in Iran. However, few studies on the relationship between this species and its habitat have been conducted. This species is recognized as one of the main food source for highly endangered species such as cheetah and leopard. In this study which lasted from fall 2009 through summer 2011, seasona...

Objective(s): To understand the role of mitochondrial respiration in cisplatin sensitivity, we have employed wild-type and mitochondrial DNA depleted Rho0 yeast cells. Materials and Methods: Wild type and Rho0 yeast cultured in fermentable and non-fermentable sugar containing media, were studied for their sensitivity against cisplatin by monitoring growth curves, oxygen consumption, pH changes ...

Background: Cryptosporidiosis is a zoonotic disease with public health importance, especially for individuals with weak immune system, such as children, elderly people and immune suppressed ones. Evaluation of the prevalence of Cryptosporidium in wild rodents such as wild brown rats could help to establish an epidemiological map of Cryptosporidiosis. The aim of the current study was to assess t...

the use of more competitive species and cultivars in small grain cereal production may help to develop production systems that require less herbicide. this study was designed to identify root and shoot characteristics of cereal seedlings that would allow distinguishing the more competitive (mc) cultivars from the less competitive (lc) ones. two growth cabinet trials were conducted using four cr...
