Survival of floret primordia initiated seems critical for the determination of grain number and yield in wheat, and understanding what determines floret mortality would help in the development of more robust physiological models of yield determination. The growth of the juvenile spikes has been frequently considered the determinant of grain number, implying that floret development would depend ...

it is suggested that cultivars of wheat (triticum aestivum l.) with regulated growth and development would be able to produce higher yields under water-limited conditions, which is crucial in future food production. water use efficiency (wue) is worthy of exploration in this regard. in this study, the effects of nitrogen fertilizer levels (0, 40 and 80 kg nha-1) and a plant growth retardant (ch...

in countries such as iran which will be faced water deficit as the main challenge in the future and the food production is going to be dependent to water recourses, wheat water-deficit tolerant and adapted genotypes release is one of the most important strategies under such a condition. in order to study the adaptation and terminal water deficit stress tolerance, fifteen bread wheat lines and c...

Requirement for replacement of energy and fuels from fossil sources by renewable sources also leads to utilization of domestic and local sources of biomass convertible to biofuel. Moreover former and actual troubles in nuclear energy generation could intensify this trend too. Renewable source for biofuel production in countries of temperate zone is also wheat as crop with relatively simply grow...

in order to study genetic variation and relationship between traits, 615 accessions of local bread wheat from wheat collection of national plant gene bank of iran were evaluated. seeds of the accessions were planted in 2.5 meter long rows in an observatory design and 17 agro-morphological traits were measured. grain yield of 5 spikes, number of tillers and number of seeds per spike were of high...

A field experiment was conducted to observe the influence of a cover crop (winter wheat, Triticum aestivum L.), and a perennial weed (dandelion, Taraxacum officinale Weber ex Wigg.), on vesicular-arbuscular mycorrhiza (VAM) inoculum potential, soil aggregation, and maize yield after one season. Mycorrhizal colonization of maize roots was higher following the autumn planting of either winter whe...
