Azospirillum brasilense is one of the N2-fixing microorganisms which, in symbiosis with the roots of cereals and other graminae, enhances growth and development of plants. In this research, wheat seeds (Triticum aestivum) of three cultivars (Ghods, Roshan and Omid) were inoculated with Azospirillum strains (Sp7 and Dol). Inoculation increased growth parameters and yield of wheat cultivars, the ...
Dry seeds of seven winter wheat varieties and one line were exposed by gamma-rays and chemical mutagens to determine their effect on plant grows and development. Next parameters have been investigated – plant survival, pollen fertility, components of yield structure. Informative value by mutation depression evaluation of all parameters has been developed. The most informative parameters for mut...
Half diallel crosses of eight bread wheat cultivars were used to estimate the genetic parameters and types of genetic control for yield and yield components, and to determine the effects of environmental factors on these parameters. Parents and their F2 hybrids were grown in a randomized block design under irrigated and stressed (terminal drought) conditions. For all traits, except for number o...
Barley developmental mutants tweaky spike (tw) with disturbed auxin pathways possess a unique feature of an increased level mouldy germinating grains (MGG), which serves as convenient model to investigate the effects plant immunity-related substances. The 2,4-dichlorophenoxyacetic acid (2,4-D), inhibitors, salicylic (SA), and trans-cinnamic (TCA) were studied using tw-WT system in surface-steri...
drought stress is considered as one of the main important factors reducing field crop yield, thus leading researchers to study the related physiological characteristics may reduce drought effects. this experiment was conducted in research farm of seed and plant improvement institute (spii) in karadj, arak and jolgeh rokh for three cropping seasons (2008-2011) to evaluate drought tolerance of br...
In order to explore the possibility of enhancing wheat productivity with limited inputs, an experiment entitled “Effect of seed soaking in nitrogen, phosphorus and herbicides solutions on yield and other characteristics of wheat” was conducted at the Agriculture Research Farm of NWFP Agricultural University Peshawar during winter2002-03. Seeds were soaked in pure water, 0.1% and 0.5% urea solut...

The advantages of free threshing in wheat led to the selection of the domesticated Q allele, which is now present in almost all modern wheat varieties. Q and the pre-domestication allele, q, encode an AP2 transcription factor, with the domesticated allele conferring a free-threshing character and a subcompact (i.e. partially compact) inflorescence (spike). We demonstrate that mutations in the m...
The lack of fresh water for irrigation in the world, especially arid and semi-arid areas is often posed as a major problem agriculture, which requires research to valorize saline water. This work aims study impact chemical correction quality on barley. corrected waters were prepared from raw by applying doses calcium represented Ca(NO3)2 4H2O according their soluble sodium content, whose aim ba...
In order to study of agronomic, physiological characteristics, drought tolerance and to identify Agro-physiological traits associated with drought tolerance, 19 durum wheat genotypes consisting of 17 advanced breeding lines and two control cultivars (Saji and Zahab) were evaluated in a randomized complete blocks design with three replicated under both stress (rainfed condition) and non-stress ...
