This study was conducted to evaluate intra-chromosome and inter hemeologous variations of grain yield and its components using two wheat substitution lines series including substitution lines of ‘Timstein’ into genetic background of ‘Chinese Spring’ and substitution lines of ‘Red Egyptian’ into genetic background of ‘Chinese Spring’ and their parents in a randomized complete block design with f...

Plant growth regulators (PGRs) are used to prevent reduction in wheat grain yield under limited moisture conditions. The effect of 3 PGRs including cycocel, salicylic acid and brassinoestroeid on yield and yield components of  four wheat cultivars (Chamran, Shiroudi, Pishtaz and Sirvan) under well watered and water stress (withheld irrigation after flowering) was examined. The experiment was ca...

 Wheat is the first among cultivated crops in terms of hectare in Iran, and is cultivated on 6.2 million hectares under variable agro-climatic conditions. Of 2.2millions hectares of wheat crop grown under irrigation system, about 30% of the areas experience the adverse effects of salinity stress, which is one of the limiting factors of wheat production in warm and temperate regions of Iran. Sel...

This study was conducted in Research Farm of Isfahan University of Technology to evaluate some of the agronomic and physiological traits and grain yield potentials of ten bread wheat cultivars using a split plot design with three replications. Main and sub plot consisted of optimum and stress moisture treatments (irrigation after 70±3 and 130±3 mm evaporation from class A pan) and wheat cultiva...

The management of soil elements by biological fertilizers is considered as an important attribute of sustainable agriculture. In order to evaluate the interaction effects of Arbuscular mycorrhizal fungi and redroot pigweed (Amaranthus retroflexus L.) on growth and yield of sunflower (Helianthus annuus L.) under water stress conditions, a field study was conducted in 2015 at School of Agricultur...

Among the crops, cereals have been special important and triticale is the most successful man made cereal. In present research, water deficit stress effects on 19 triticale genotypes (X Triticosecale wittmack) and two wheat cultivars (Triticum aestivum), Shiraz (sensitive to water deficit stress) and Kavir (tolerant to water deficit stress) were tested. Therefore, two separate field experiments...

In order to determine the best index for evaluating maize genotypes, 28 maize hybrids were evaluated in two planting dates, 6 July to coincide heat stress with pollination time and 27 July as normal planting to avoid high temperature during pollination and grain filling period, using a randomized complete block design with three replications, in Shushtar city, in 2008. Results showed that in st...
