Sainfoin (Onobrychis vicifolia Scop.) is one of the most important forage legumes cultivated as high quality forage. Fifty three species have been identified in this genus in Iran. A field experiment was conducted using randomized complete block design to compare yield and forage quality of 20 populations of sainfoin in Isfahan Agricultural and Natural Resources Center, Iran during 2013 – 2014....

a geometric morphometric study of the genus erodiontes was carried out using the elliptic fourier method to demonstrate the effect of vicariance on populations of these psammophilous species. four populations of erodiontes, comprising e. aelleni and e. pfaundleri, were sampled from chartaghi, aboozeidabad, meser and hojatabad. differences between the shapes of the conspecific populations are mi...

Genetic variation among the individuals is considered as an important tool for conservation of livestock animals. This study was conducted to analyze the genetic variation, phylogenetic relationship and paternal lineages among Iranian dog populations using seventeen autosomal and Y chromosome-specific microsatellite markers. Total DNAs of the samples were extracted and applied for genotype anal...

twenty accessions of cultivated grass pea (lathyrus sativus l.) and wild species of lathyrus l.collected from western and southern regions of iran were evaluated for their mitotic metaphase chromosomalcharacteristics. all populations comprising 16 populations of cultivated l. sativus and 4 wild populations oflathyrus l. were diploid, 2n=2x=14 chromosomes. there were significant variations among...

The extended use of glyphosate resulted to its reduced efficacy against increasingly problematic weeds, such as Conyza spp. The objectives of this study were to determine the occurrence of glyphosate resistance in horseweed (C. canadensis) and fleabane (C. albida) populations in Greece, to evaluate the effect of weed growth stage on glyphosate efficacy under controlled environmental condit...

In order to investigation of chromosomal variation in various populations of Aegilops cylindrica from northwest of Iran, the karyotype of each populations was prepared using aceto-iron-hematoxilin staining and different chromosomal characteristics were measured. The results showed that the karyotype of these populations consisted of seven pairs of metacentric, three pairs of submetacentric and ...

Abstract Yellowfin seabream (Acanthopagrus latus), an important economical species and popular market fish found in the coastal water of Persian Gulf. In this study, eight microsatellite loci were used, population structure and genetic diversity of this species was studied in six fishing area in the Persian Gulf. Alleles observed in different stations were between 7 to 12 with an average of  9...

In this study, 45 Pleurotus isolates with a wide range of geographical origins (in five provinces of Iran: Isfahan, Chaharmahal Bakhtiary, Kohkiloye boyrahmad, Lorestan and Fars) were collected. A random amplified polymorphic DNA polymerase chain reaction (RAPD-PCR) was used to assess the genetic diversity in ten populations of the Pleurotus eryngii complex. The use of ten primers allowed the p...

Objectives: Study of hidden populations such as Injection Drug Users (IDU) due to their exposing to high risk diseases and their roll in public health is very crucial. Conventional statistical methods for sampling these populations are not applicable because of the restrictions these populations are faced. Despite the introduction of respondent driven sampling as a successful method for samplin...
