     Triticum boeoticum wild wheat is a remarkable gene pool to environmental stress resistance. It is one of the most valuable species of the Triticeae tribe for improving wheat cultivars to moisture-stress. This research was carried out to assess the changes and responses of different traits of 10 accessions of Triticum boeoticum under non-stress and imposed moisture stress conditions in 2015...

Limited time for crop residue decomposition and complete seedbed preparation in double-cropping necessitates reduced tillage which is associated with its shortcomings. Information about seedbed preparation aspects in double-cropping of wheat and mungbean in Isfahan is lacking. For this reason, the effects of various seedbed preparation methods on growth, seed yield and yield components of mungb...

BACKGROUND Grain yield is a key economic driver of successful wheat production. Due to its complex nature, little is known regarding its genetic control. The goal of this study was to identify important quantitative trait loci (QTL) directly and indirectly affecting grain yield using doubled haploid lines derived from a cross between Hanxuan 10 and Lumai 14. METHODOLOGY/PRINCIPAL FINDINGS Ten...

aegilops triuncialis l. (2n=4x=28; ctctutut) is one of the tetraploid aegilops species harboring valuable genes for resistance to many biotic and abiotic stresses. in the present study the bread wheat cultivars mv17, navid, omid, pishgam, zarin were crossed with an accession of ae. triuncialis and the resulted f1 and f2 (obtained by the selfing of f1 plants) hybrids studied using the convention...

Harmonic analysis is applied to analyze the transmission of bandlimited signals via spike trains generated by a pair of leaky integrate-and-fire (LIF) model neurons organized in a push-pull, or ‘on/off’, configuration. It is found that lowpass signals can be transmitted with only moderate distortion utilizing mean spike rates with many spikes per signal coherence time. The transmission of bandp...

The composition of the translocates reaching the seeds of pea plants having various nitrogen (N) nutrition regimes was investigated under field situations. Sucrose flow in the phloem sap increased with the node number, but was not significantly different between N nutrition levels. Because N deficiency reduced the number of flowering nodes and the number of seeds per pod, the sucrose flow bleed...

breeding for drought stress is one the important purposes in wheat cultivars breeding programs. grain yield under drought stress is depended on phonological, morphological and physiological features. in order to investigate the general and specific combining ability and genes function under drought stress in three and two bread wheat lines and cultivars respectively, diallel one way cross was p...

terminal heat stress is the most widespread heat stress in the world. in order to evaluate the effect of heat stress on yield, yield component, and mopho-phenological traits of barley, 10 barley genotypes including the 2-row genotypes: mahour, khoram, nimrooz, abidar and 6-row genotypes: yousef, rihan 03, izeh, zahak, nosrat, jonoub were tested under normal (optimum sowing date) and heat stress...

To further elucidate the regulation of dormancy release, we followed the natural afterripening of Virginia-type peanut (Arachis hypogaea L.) seeds from about the 5th to 40th week after harvest. Seeds were kept at low temperature (3 +/- 2 C) until just prior to testing for germination, ethylene production, and internal ethylene concentration. Germination tended to fluctuate but did not increase ...

The article presents the results of studying influence quantitative traits on barley plant performance. Thirty typical plants were selected for each 28 genotypes spring two-row cultivars and their height, productive tillering capacity, spike length, number weight kernels from main spike, 1000-kernel weight, performance measured. As a result, we found significant positive correlations between ca...
