drought stress has been well documented as an effective parameter in decreasing crop production, developing and releasing new varieties which are adaptable to water deficit conditions can be a constructive program to overcome unsuitable environmental conditions. in order to evaluate the adaptation of rice genotypes to drought stress and to identify the tolerant and sensitive genotypes, 15 genot...

in order to providing selection indices using heritability and correlation effective traits on yield and multiple regression an experiment was conducted by 265 f3 families as well as parents and f1 related to gharib × khazar population in 2009 at gonbad high education center fields. days to repining (0.97) and panicle number and flag leaf length (0.66) had maximum and minimum heritability, resp...

seed weight (sw) in oilseed rape (brassica napus l.) is determined during the seed filling period (sfp). a great proportion of variation in sw is associated with environmental conditions in this period. to quantify factors determining sw in open pollinated (op) and hybrid cultivars of oilseed rape, 12 field experiments were conducted at agricultural research station of gonbad, iran, during 2000...

the family magnaporthaceae considered as a single-family placed in the order magnaporthales. currently, three distinct clades are phylogenetically distinguished in this order that one is referred as the pyriculariaceae. the pyriculariaceae is characterized as a novel family having new genera, new species, new combinations and neotypification (basionym). to taxonomically evaluate this family, an...

genetic× environment interaction for genetic, plant breeder and animal breeding is very important. insight of g×e helps to plant breeders for genotypes evaluating precisely until select the best genotypes and release the stable genotypes for general and special environments. present study in order to achievement to high yield and yield stable in the different years, was done on the 20 advance b...

This work presents the application of a geostatistical-based modeling approach for building up electrical properties acquired from a geophysical electrical tomography survey deployed for the purpose of porphyry Cu exploration at the Takht-e-Gonbad deposit, in the central domain of Iran. Electrical data were inverted in 2D along several profiles across the main favorable zones of Cu-bearing mine...

regarding the necessity of regional integrated development, analyzing the dependency of human habitats in region-level, is the main duty in every planning. therefore, deprivation and inequality reduction is an important matter, due to its economic and social consequences and needs proper attention. in fact, to achieve comprehensive development and progress in the future; requires the recognitio...

quantitative serum level measurements of gc , cp , c3 , igg , iga and 1gm were carried out on 102 patients with esophageal carcinoma following laryngectomy, in comparison with 66 healthy individuals as controls, in gonbad area, north east of iran. the procedure of radioinimuno-diffusion by standard m partigen plates was used for the measurements. a significant decrease was observed in gc level ...

background: the aim of this study was to determine the prevalence, intensity, and species of internal and external parasites of native fowls from golestan province, north of iran. methods: during 2007, different organs of 26 and 24  adult female native fowls  collected   from hu­mid parts (gorgan, kord kooy, ramian and bandar gaz) and dry regions  (gonbad kavoos, and ban­dar torkaman) of golest...
