spotted amber ladybird, hippodamia variegata (goeze, 1777) (coleoptera: coccinellidae) is an important predator of aphids and some other insect pests. since shape and size variation may affect biological characteristics of an insect, multivariate analysis of shape variations in four geographically isolated populations of h. variegata (isfahan, shahrekord, shiraz, yasuj) was performed based on e...

Hot pepper (Capsicum spp.) is an economically important spice widely cultivated and consumed in Ethiopia. In spite of its wide importance, there is no information available on the molecular genetic diversity of this crop. Cultivars characterization is an important link between the conservation and utilization of plant genetic resources in various breeding programs. Using five ISSR prim...

Little information is available regarding genetic variation in wild wheat relatives from Iran. In this study, genetic diversity of 36 populations of wild einkorn wheat, Triticum boeoticum, was studied using amplified fragment length polymorphism (AFLP) primer combinations. Seventeen AFLP primer combinations led to amplify 979 scorable fragments ranging from 50 to 500 bp and of these, 429 (44%) ...

natural, renewable, biodegradable and low pollution hemp fibers are an alternative to trees xylem and artificial fibers. in this study, xylem and bast fiber properties of six iranian hemp populations including length, width, wall thickness, lumen width and wall index were measured and compared. to this purpose, collected population seeds from different parts of iran were nursed in a controlled ...

in this study 21 coriander populations the accumulated from different regions of iran was conducted¬ augmented design at shahid chamran university of ahvaz. some of morphological characteristics (time of emergence, plant height, fresh and dry weight, seed weight)and anti¬oxidant (carotenoids, vitamin c, catalas and proxidase) of these populations were evaluated. the analysis of variance showed ...

retrotransposons (rtns) constitute informative molecular markers for plant species because of their ability to integrate into a multitude of loci throughout the genome and thereby generate insertional polymorphisms between individuals. in the present study, rtn-based molecular markers, irap (inter-retrotransposon amplified polymorphism) and remap (retrotransposon-microsatellite amplified polymo...

introduction: cephalometry is an efficient tool for anthropometric studies. this study sought to assess facial dimensions and types of adults residing in qazvin (iran) and dera ghazi (dg) khan (pakistan). methods: in this cross-sectional study, a total of 300 ethnic populations of qazvin and 365 ethnic populations of dg khan aged between 18-55 years were randomly selected and evaluated. the sub...

it has been postulated that the building of the manjil and tarik dams on sefidroud river has led to the body shape variation of capoeta gracilis in up- and downstream populations due to the isolation. in this study, geometric morphometric approach was used to explore body shape variations of capoeta gracilis populations in up- and downstream manjil and tarik dams in sefidroud river from south o...

the aim of this study was to access the genetic differentiation of paraschistura sp. in kheirabad and brim rivers (zohreh river system, persian gulf basin), iran. for this purpose, 60 samples including 30 male and 30 female samples from each river were collected. a total of six microsatellite loci (bbar4, bbar7, ic228, ic230, ic434 and ic720) were used and all of them showed high polymorphism (...
