Drought stress can play an important role in limiting crop productivity and disturbing different stages of plant growth especially at seed germination in arid and semiarid regions. Breeding for drought tolerance at germination stage can enhance the number of seedlings, resulting in a higher yield of grain in rapeseed. In this research 32 cultivars of rapeseed were evaluated for drought toleranc...

Drought stress is one of the most important abiotic stresses in crops that can reduce yield and yield components in terms of time, duration and severity of the stress. Current research was carried out in order to evaluate drought stress tolerance in rice genotypes. Experiment done in two separate schemes using randomized complete blocks design with three replications in Research Field, Faculty ...

  Background and Aim : The aim of the present study was to examine the personality variables of morning-type, rigidity, neuroticism , extroversion, openness, agreeableness and conscientiousness as predictors of shift work tolerance in an industrial company in Ahvaz.   Methods: The sample consisted of 245 shift workers which were selected by the use of stratified random sampling. At first the pa...

Objective: This study was aimed at predicting tendency to drug use based on behavioral activation and inhibition systems, cognitive flexibility, and distress tolerance among students. Method: The research method used in this study was descriptive and correlational. The statistical population of this study included all high school students in Ardabil in the academic year of 2015-2016. From among...

Asiyeh Shariatmadar , ahra Gharavi Aim: The goal of the present research was to compare cognitive distortions in individuals with physical-movement handicap whose distress tolerance is high or low. Method: The method used in this research was of ex post facto causal-comparative type. Statistical population was all of the individuals with physical-movement handicap in Tehran, Iran, during the ye...

In the present study, in order to evaluate the drought tolerance indices and their relationship with ISSR markers, 12 rapeseed genotypes were studied using a factorial experiment based on completely randomized block design under the three irrigation treatments (control and irrigation after drainage of 60 and 85% moisture content) in the greenhouse of Mohaghegh Ardabili University, Iran. Drought...

Regarding the insufficient water resources, developing of cultivars with high tolerance to water deficit can be very effective to optimize water consumption. To identify maize hybrids with higher tolerance to water deficit, 52 single cross hybrids were field evaluated according to a randomized complete block design with three replications in each irrigation regime. The hybrids were produced thr...

In order to determine the most effective indices for quantifying drought tolerance and identify genotypes that are tolerant to water stress in bread wheat, 50 bread wheat genotypes were compared in a randomized complete block design with three replications under both the non-stress dry farming with two complementary irrigation and the water stress dry farming conditions in Khorramabad, Iran. An...
