to cope with cold stress, winter cereals regulate their development through adaptive mechanisms such as vernalization requirement. eight wheat and four barley cultivars were planted to determine the relationship between vernalization fulfilment and expression of cold tolerance under both field and controlled conditions. cultivars were planted at maragheh and karaj agricultural research stations...
lead to continuing effects for increasing extensive of yield by means of advanced agronomic operations and selection of high yielding resistant genotypes. there fore, due to evaluation and determination of best effective traits in improvement of yield and grain quality of local populations of winter wheat, an experiment was carried out in uremia agricultural research station, on 30 local popula...
The Alvand complex (Hamedan province) comprises several bodies ranging from acidic to intermediate and basic compositions intruded in the regional metamorphic sequence of the area (the Hamedan phyllites) during various magmatic episodes in Jurassic. In northern part of the complex (the Cheshmeh-ghasaban area) there are some outcrops of hornblende gabbro and olivine gabbronorite. The olivine-gab...
During the last two decades, various medicinal plants have been studied for their possible antimicrobial activity to discover new antimicrobial agents capable of resolving problems such as the development of drug resistance in pathogenic microorganisms as well as the side effects of some present antibiotics. In this study, the antibacterial activity of methanolic extract of T. pubescens (rich i...
The karstic Rijab Spring with an average discharge of 3290 l/s is located in the Alvand River basin in the northwest of the Zagros, Iran, which drains Asmari formation. To investigate groundwater flow in the catchment area of the Spring, the physicochemical parameters include major cations and anions, discharge, EC, pH, and temperature were studied from September 2000-2002. The results indicate...
Intrusion of the Alvand plutonic complex into the pelitic and sim-pelitic rocks of the Tuyserkan area has caused the development of a thermal aureole in the Sarabi area. The rocks within the aureole are thermally metamorphosed and formed different types of hornfelses. High-grade metamorphic rocks with chemically suitable compositions were melted adjacent to the contact due to the heat from the ...
Background and purpose: The aim of this study was to evaluate the quality of wastewater treatment plant effluent in Qazvin (Alvand) industrial area for discharge into the environment and reuse. Materials and methods: The study was conducted over a period of nine months in 2015-2016. Ninety samples of wastewater were collected to determine the concentrations of BOD5, COD, TSS, TC, FC, and hea...
Zamanabad area is located in southern of Hamedan Province and belong to Sanandaj-Sirjan magmatic-metamorphic Zone. Lithologic units of this area comprising slate, phyllite, andalusite-garnet bearing schists, metamorphic complex including sillimanite bearing schists, hornfels, pegmatitic unit and recently alluviums. The most important of geological unit is Alvand granitoid pluton at age middle J...
