genetic variation of 20 genotypes (15 exotic collected from icarda, and 5 endemic collected from various regions of iran: ardebil, oshnaviyeh, qazvin, shahre kord and mashhad) were studied during the 2007-2008 growing season, using morphological and phenological traits. the resultant data were examined for normality test and were then analyzed according to randomized complete block design (rcbd...

identification of genes affecting energy balance, milk yield and feed intake is an interesting area of researches in animal breeding. leptin gene polymorphism is associated with key economic affair. considering rich resources for animals, in our country, accomplishing a few assays to identify a gene that controls her traits with molecular genetics, and identifying the candidate genes in sheep b...

biodiversity refers to all forms of living animals, plants and microorganisms and agro-biodiversity is a component of biodiversity that represents diversity in arable lands. the aim of this study was to determine the biodiversity status of agro-ecosystems of shahr-e-rey city located in south of tehran, through calculating species richness index using rarefaction method. to the collect required ...

in this investigation, using mann – kendall graphical-statistical test, which is one of the proposed methods of world meteorological organization (wmo) for time series analysis, the change trend of long – term mean of annual minimum and maximum temperatures in iran will be studied. to evaluate this trend and access a suitable pattern in this situation, average of annual minimum and maximum ...

introduction two main principal aspects for the genesis of porphyry copper deposits have been determined. the first genetic model concerns the petrologic and geochemical processes and the other relates the genesis to crustal deformation and geodynamic conditions (kesler, 1997). recent studies (e.g., padilla garza et al., 2001) show that the generation and emplacement of porphyry copper deposits...
