Drought is one of the most destructive abiotic stresses worldwide that affects growth, development and final yield of crops. Reactions of thirteen rainfed spring 2-row barley genotypes and cultivars of cold areas of Iran to water stress were evaluated based on phenological, physiological and morphological traits. The experiment was carried out as factorial experiment based on a randomized com...
Barley (Hordeum vulgare L.) as one of the main crops is important economically for Iran. Genetic diversity and it`s evaluation is foundation of plant breeding projects. Awareness about genetic variation is effective in selection of parental lines for future breeding programs. This study was aimed to evaluate both morphological and physiological characteristics followed by classification of 18 b...
Identification and introduce of high potential and water deficit stress tolerant is one of effective methods that caused to economic production beside other methods of water deficit management. In order to identification of barley lines, 9 barley elite lines and Bahman variety (check) studied under full irrigation and water deficit stress conditions in season cropping years 2013-2015. The resul...
to determine the correlation between important traits with yield in barley through path analysis for selecting high yielding lines, three new lines of barley resistant to cold (c-81-13, c-81-11, c-81 -15), compared with valfajr (as control) were studied. this experiment was conducted in a randomized complete block design with three replications, during 2008 to 2010 in boyer ahmad city.a number ...
in the new age, in regard to human success in education in the globalizing world, one can consider english proficiency and individual differences as two important issues. in efl settings, reading skill plays an important role in education. it seems that using multiple intelligences theory in efl classes which values individual differences by tapping different intelligences, can be rewarding. as...
Drought is an important factor limiting crop production in arid and semi-arid conditions. Drought indices which provide a measure of drought based on yield loss under drought condition in comparison to normal condition was used for screening drought-tolerant genotypes. This study was conducted to determine drought tolerant genotypes with high yield in stress and non-stress conditions. Ten barle...
The barley HvAACT1 gene codes for a citrate transporter associated with tolerance to acidic soil. In this report, we describe a single nucleotide polymorphism (SNP) in the HvAACT1 coding region that was detected as T-1,198 (in genotypes with lower root growth on acidic soil) or G-1,198 (greater root growth) and resulted in a single amino acid change (L/V-172). Molecular dynamic analysis predict...
evaluation of mechanisms of barley genotypes tolerance and antixenosis schizaphis graminum (rondani)
schizaphis graminum (rondani) (hem.: aphididae) is one of the seriously injurious pestsof cereals particularly of barley. the population of the pest has beenon the increase in recentyears. besides chemical control, another practically suitable method of controlling the pest isthe use of resistant barley genotypes. in this research, 47 advanced lines along with 13 cultivarswere screened in their...
MicroRNAs are short molecules of 21-24 nt in length. They are present in all eukaryotic organisms and regulate gene expression by guiding posttranscriptional silencing of mRNAs. In plants, they are key players in signal transduction, growth and development, and in response to abiotic and biotic stresses. Barley (Hordeum vulgare) is an economically important monocotyledonous crop plant. Drought ...
The amplified fragment length polymorphism (AFLP) assay is an efficient method for the identification of molecular markers, useful in the improvement of numerous crop species. Bulked Segregant Analysis (BSA) was used to identify AFLP markers associated with water-stress tolerance in barley, as this would permit rapid selection of water-stress tolerant genotypes in breeding programs. AFLP marker...
