The aim of this study was to determine the drought tolerance control loci in growth stage in bread wheat. In this regards 99 doubled haploid lines with their parents were evaluated in a randomized complete block design with three replications in two drought stress levels. Genotypes mean square for all traits in two environments was significant. Thirty three SSR markers and 24 TRAP markers which...
In this study the effects of drought stress on proline, protein, chlorophyll a/b, ascorbate and dehrydroascorbate were investigated in Akri and Mobil cultivars of tomato species. The seeds were cultured at 23 °C with 15-16 hours light period and irrigation was done based on field capacity control (FC), mild drought stress (⅔ FC) and severe drought stress (⅓ FC) under greenhouse conditions. Afte...
In order to study the physiological growth indices and yield of green bean in response to vermicompost amendment under drought stress conditions a field experiment was conducted in Dezful, southwest of Iran during 2016 using a split plot design in a randomized complete block design with four replications. Application of drought stress by irrigation interval method at four levels of irrigation (...
To evaluate genetic diversity and to determine the relationships between yield and other importante traits among bean genotypes, an experiment was conducted in Random Completely Block Design (RCBD) with three repetitions under both normal and drought stress conditions in 2015-2016 crop season on 30 bean genotypes at Tehran University research farm. The results of variance analysis indicated hi...
environmental stress, particularly drought stress can play an important role in reducing plant growth especially during the germination stage in arid and semi-arid regions in iran. for cultivation of medicinal plants in arid and semi-arid areas, the assessment of their tolerance is very important. in this research, in order to evaluate the effects of salicylic acid pretreatment on enhancement o...
Drought stress is one of the most important factors limiting the survival and growth of plants in the different habitats of Iran. Detailed knowledge about the ecophysiological responses of native plants to drought stress could contribute to the success of breeding and re-vegetation programs. Six wild populations of Anthemis tinctoria, were assigned to four drought treatments, i.e. well...
Background and objectives One of the main causes of plant growth and development disorders is the presence of adverse environmental conditions such as drought, which leads to stress in plants and endangers their survival. Recent research, however, recommends the use of soil microorganisms, especially plant growth-promoting bacteria, which are involved in plant growth as well as the nutrient cy...
Drought stress as an abiotic stress causes different biochemical and physiological responses in plants. To study changes in chlorophyll, total soluble protein and antioxidant activity due to drought stress, we conducted an experiment on five durum wheat varieties (selected from the Seed and Plant Improvement Institute in Karaj) at research greenhouse of Imam Khomeini International University in...
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...
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...
