In order to identify drought tolerant germplasm, 97 bread wheat landraces, mostly Iranian genotypes, were evaluated in two separate experiments of normal and drought stress conditions in the field of Agriculture and Natural Resources Research Center of Varamin. The experiments were performed in lattice statistical design with three replications. Drought conditions in the stress experiment was e...
Extended Abstract Introduction and Objective: Due to the water resources limitation required for agriculture in Iran, providing effective methods to reduce the negative effects of drought on crop yield is one of the important studies to plant breeding. Drought tolerance in crops is very important. By using different cultivars of crops that are able to produce relatively good yield in drought s...
In order to evaluate the genetic diversity of oily sunflower lines, screening drought tolerance indices and identification of drought tolerant lines, 100 oily sunflower lines were evaluated in a simple lattice design under both well-watered and water-limited stressed conditions in 2016. Based on the potential (Yp) and stress (Ys) yield, quantitative drought tolerance criteria such as: mean prod...
Breeding of rice for drought tolerance requires proper evaluation and analysis of genetic diversity in breeding populations related to drought tolerance. In order to identify indices for tolerant and sensitive rice genotypes to drought stress, an experiment with 59 genotypes of rice was conducted based of a complete block design with three replications in non-stressed (flooding) and stressed co...
the first step in identification of genes which control traits in stress and no stress conditions is localization of chromosomal related to traits. in order to locate the genes controlling drought resistance and screening quantitative indices of drought resistance in wheat, substitution line series of hope into the genetic background of chinese spring (cs) were tested in a randomized complete b...
in order to evaluate and drought tolerance selection in cowpea genotypes and to identify the best indices for drought tolerance, an experiment was conducted at research field university of tehran in karaj during 2011-2012 growing season. in this study, 31 cowpea genotypes were evaluated in a randomized complete block design (rcbd) with three replications under normal irrigation (non- stress) an...
Drought stress is one of the most important environmental stresses that have limited the production of wheat, especially in arid and semi-arid regions of the world. To recognize drought tolerant rain-fed wheat genotypes and to determine the best tolerance/susceptibility indices, a study was conducted at the Agricultural Research Station of Miandoab for two cropping years (2013-15). The experime...
Objectives: Heart rate variability (HRV) has been used to assess sympathetic and parasympathetic modulation of heart rate. Chronic stress relates to reduced HRV. Malocclusion has effects on quality of life, which can lead to chronic stress. Therefore, we hypothesized that malocclusion, as chronic stress, may contribute to reduced HRV. The aim of this study was to investigate the relationship be...
This paper presents a case study to determine the efficiency of the currently used heat stress indices in correlation with wet bulb globe temperature (WBGT) as a permissible index at a foundry plant and to evaluate the extent of the physiological responses such as heart rate and body temperature in correlation with heat stress indices. The field consisted of a foundry plant where a shift w...
In order to evaluate the response of 20 lines and cultivars of soybean to water deficit stress, an experiment was conducted at Agricultural Research Station of Gorgan in 2011 and 2012. For this Purpose, 2 separate experiments was conducted, each one in randomized complete block design, with 3 replications. In first experiment, all soybean genotypes were irrigated based on 50 mm evaporation from...
