chickpea is commonly grown in large scales in the western part of iran (kermanshah, hamedan, lorestan and chahar mahal & bakhtiari) and it forms a symbiotic relationship with rhizobia which promotes legumes growth through nitrogenfixation. therefore, it is important to evaluate the population genetic structure of rhizobia nodulating chickpea in various areas to manage extension of chickpea cult...

this experiment was conducted to evaluate the effect of nursery establishment under plastic cover on yield of some rice cultivars at lordegan region in 2007. experimental design was a split plot with a randomized complete block with three replications. four rice cultivars (hashemi, hasani, saleh and native) were seeded at three seedling date (14 april, 5 may and 15 may). two first planting date...

to modeling of suitability iranian oak site to establish coppice regenerations, chahartagh forest reserve, ardal region, chaharmehal and bakhtiari province, southern zagros forest, and southwest iranian state was selected. to modeling suitability iranian oak used the physiographic element, soil depth, climatology and distance from village selected. to this study used the raster formats by pixel...

Background Genetic factors are candidates for about 30% of male infertility with sperm production-related abnormalities. Y chromosome microdeletions are responsible for around 10% of male infertility. These microdeletions generally occur in azoospermia factor on the Yq. That is often associated with the quantitative reduction of sperm. Objective The aim of this cross-sectional study was to de...

original article   introduction: direct sunlight and increased heat load influence mental and physical health of workers negatively and result in performance impairment. activity reduction is a natural body response to increase in internal body temperature, and a compensatory mechanism to make body balanced. this study was carried out to estimate productivity loss due to heat exposure among ira...

Background: HLA genes are highly polymorphic and certain alleles are frequent only in specific populations. Therefore, HLA is a unique tool for studying the genetic relationship between different populations. Iranians are ethnically diverse people and one of the major ethnic groups in Iran is Lur population inhabiting along the central and southern parts of Zagros Chain Mountain. Objectives: Ge...

chaharmahal and bakhtiari province is one of the 31 provinces of iran and located on the southwestern part of the country. its capital is shahrekord. it has an area of 16,332 square kilometers and a population of 857,910. to study of human development used the surplus biocappacity (sb) and human development index (hdi). this research accrued in the shahr-e-kord, boroojen, farsan, ardal, lordega...

spatial pattern of trees can possibly indicate stand history, population dynamics, and species competition. this research was investigated in the chahartagh forest reserve, ardal region, chaharmehal and bakhtiari province, central zagros forest, and southwest iranian state. in this study 53 hectare of the study area was selected and perfect inventory.  information includes the position and kind...
