Drought is one of the major environmental stresses that adversely affect crop growth and productivity worldwide. For evaluation of drought stress on grain yield, yield components and drought tolerance indices, 20 genotype of rapeseed (Brassica napus L.) was studied in an experiment based on a randomized complete blocks design with three replications in two different conditions (stress and non-s...
This study was designed to provide estimates of the degree to which stress-ulcer susceptibility in the rat is genetically determined; whether that characteristic is a dominant, intermediate, or recessive trait; and how many genie units may be necessary to account for the observed trait variability. Parental populations of Sprague-Dawley rats and animals of the sixth generation of a stress-ulcer...
In order to assess tolerance to drought and resistant and susceptible genotypes, 86 genotypes of native and commercial wheats were evaluated in germination stage with a factorial experiment in a completely randomized design with three replications. Two levels of osmotic potential of zero (control) and -4 bar. PEG 6000 were used to create the tension of the material. Different morphological trai...
Coriander is an annual plant belonging to Apiaceae family that its yield is affected by drought stress. Three experiments (normal irrigation regime, sudden drought stress and gradual drought stress) were conducted according to a randomized complete block design with three replications in 2015 to introduce the most drought tolerant Iranian coriander ecotypes based on several economical traits, a...
The aim of this study is to produce landslide susceptibility mapping by probabilistic likelihood ratio (PLR) and spatial multi-criteria evaluation (SMCE) models based on geographic information system (GIS) in the north of Tehran metropolitan, Iran. The landslide locations in the study area were identified by interpretation of aerial photographs, satellite images, and field surveys. In order to ...
In this study, Vanak catchment because of high sensitivity to landslide was selected. Then with geological, topographic maps and field survey, Landslide hazard map was prepared using GPS as dependent variables. A total of 110 landslides were mapped in GIS out of which 77 (70%) locations were chosen for the modeling purpose and the remaining 33 (30%) points were used for the model validation. Th...
Abstract Mechanical stress acting in the Earth’s crust is a fundamental property that important for wide range of scientific and engineering applications. The orientation maximum horizontal compressive can be estimated by inverting earthquake source mechanisms measured directly from borehole-based measurements, but large regions continents have few or no observations. Here we present an approac...
abstract water deficit is a major problem for the successful production of agricultural products in iran. this research was conducted to evaluate drought tolerance indices and identifying drought tolerant cultivars of canola. twenty eight canola cultivars were sassed implementing complete block designs experiments in normal and drought stress conditions at isfahan university of technology resea...
