Effects Of Seeding Rates On Competition Indices Of Barley And Vetch Intercropping Systems In The Eastern Mediterranean, Şaban Yilmaz, Ali̇ Özel, Mehmet Atak, Mustafa Erayman
Turkish Journal of Agriculture and Forestry
Forage mixtures are common agricultural practices for the energy and protein needs of animals. In this study, common vetch (Vicia sativa L.), Hungarian vetch (Vicia pannonica L.), and barley (Hordeum vulgare L.) mixtures in different seeding rates were investigated in terms of forage yield and quality. In order to evaluate the effect of vetch, cereal intercropping and the competition/economic indices of 8 different legume-barley mixtures, along with their pure stands, were assessed during the 2008-2009 and 2009-2010 growth seasons in the Eastern Mediterranean region of Turkey. The field experiment was arranged as a randomized complete block design with 3 replications …

Molybdenum cofactor sulfurases (MCSUs) are important enzymes for plant development and response to environmental queues, including processes such as nitrogen metabolism and regulation of the abscisic acid levels in plant tissues. We cloned and sequenced MCSU gene from barley and performed in silico comparison with rice, tomato, and Arabidopsis. Physico-chemical properties and subcellular predictions were found to be similar in different plant species. All MCSUs had three critical domains: aminotransferase class-V (Pfam: PF00266), MOSC N-terminal beta barrel (Pfam: PF03476), and MOSC (Pfam: PF03473). Secondary structure analysis revealed that random coils were the most abundant, followed by α-helices and extended strands. …

Genetic variations are the raw materials of plant breeding and have been increasingly narrowed due to various reasons. Landraces are good sources of genetic variation, but need to be characterized first. This study was conducted to determine the levels of genetic variation in 3 barley materials originated in Turkey, all known as Tokak. Of the 3 materials used, PI 470281 is a landrace and CIHO 10093 is a pure line. The third is Tokak 157/37, a major cultivar of Turkey considered to be a landrace. In order to detect the levels of polymorphism within and among these materials 30 SSR …

DNA microarrays, being high-density and high-throughput, allow quantitative analyses of thousands of genes and their expression patterns in parallel. In this study, Barley1 GeneChip was used to investigate transcriptome changes associated with boron (B) toxicity in a sensitive barley cultivar (Hordeum vulgare L. cv. Hamidiye). Eight-day-old aseptically grown seedlings were subjected to 5 or 10 mM boric acid (B(OH)_3) treatments for 5 days and expression profiles were determined with DNA microarrays using total RNA from leaf tissues. Among the 22,840 transcripts - each represented with a probe set on the GeneChip - 19,424 probe sets showed intensity values greater than …

This study was conducted with barley in greenhouse conditions in order to investigate seed inoculation with 5 different N_2-fixing (Bacillus licheniformis RC02, Rhodobacter capsulatus RC04, Paenibacillus polymyxa RC05, Pseudomonas putida RC06, and Bacillus OSU-142) and 2 different phosphate-solubilising (Bacillus megaterium RC01 and Bacillus M-13) bacteria in comparison to control and mineral fertiliser (N and P) application. Among the strains used in the present study, 6 plant growth promoting rhizobacteria (PGPR) stimulated indole acetic acid (IAA) production and 3 of them stimulated phosphate solubilisation; all bacterial strains fixed N_2 and significantly increased the growth of barley. Available phosphate in soil was …

The Combining Abilities Of Some Barley ( Hordeum Vulgarel.) Genotypes Under Saline Conditions, Riza Yilmaz, Cahi̇t Konak
Turkish Journal of Agriculture and Forestry
The salt tolerance of eight barley genotypes and their 15 F1 hybrid populations were investigated in line x tester analysis for seedling traits in greenhouse and generative stage characteristics in saline fields. The data indicated that there was sufficient genetic variability among genotypes for salt tolerance in barley. The MENTA "S" genotype for general combining ability and Tokak 157/37 x ZARZA "S", Quantum x No.56000/MISC-233 and Kaya-7794 x ZARZA "S" crosses for specific combining ability had positive and significant estimates both in greenhouse and field conditions. It was determined that spike length, number of grain per spike, single spike yield, …

Heterotic Effects Regarding Salt Tolerance In Some Characters Of Barley (Hordeum Vulgare L.), Riza Yilmaz, Cahi̇t Konak
Turkish Journal of Agriculture and Forestry
The salt tolerance of some barley genotypes and their cross populations were evaluated at seedling stage in a greenhouse, and at the generative stage in a saline field in line x tester analysis. Promising crosses were determined through comparison of heterotic effects. Tokak-157/37 x LIGNEE-640, Quantum x MENTA "S" and Kaya-7794 x MENTA "S" were found to be superior cross combinations with respect to salt tolerance in both greenhouse and field conditions. In the cross populations, the highest- positive heterosis values were 25.00% for seedling emergence, 26.53% for root length, 66.27% for shoot length to root length ratio, 9.39% for …

The Effect Of Seed Size And Nitrogen On Root And Shoots In The First Development Stage Of Barley, Fahri̇ Sönmez
Turkish Journal of Agriculture and Forestry
This research was conducted to determine the effects of seed size and nitrogen fertilization on seedling growth of barley cultivars Angora and Cumhuriyet-50 at Çanakkale Onsekiz Mart University, Faculty of Agriculture in 1997. According to results of the research, there were significiant differences between Angora and Cumhuriyet-50 cultivars for seedling length (in field research), leaf number, dry weight of above-soil surface organs, and root/dry weight ratio of above-soil surface organs. Seed size significiantly affected seedling length (in pot research), leaf number (in pot research), dry weight of above soil surface organs and root-dry weight, and large seeds produced heavier seedlings. …
