Objective: In order to study genetic variation and effect of drought stress on grain yield and some morphological traits in chickpea, an experiment was conducted on 64 genotypes during 2013-2014 cropping season at deputy of Kermanshah Sararood Dry Land Agricultural Research Institute, located on the western part of Iran. Methods: The experimental design was a randomized lattice design with tow ...

To investigate genetic variation, and identification of tolerant genotypes according to quantitative indices of drought tolerance, 8 sesame genotypes were tested in a randomized complete block design with three replications under optimum and limited irrigation at the Research Station of College of Agriculture, Shiraz University. Based on the potential yield and yield under stress, quantitative ...
abstract: evaluation of drought tolerance for 20 barley genotypes were conducted under normal irrigation and terminal stress condition by withholding irrigation at the time of 50% flowering. drought effect on grain yield and plant total mass traits was studied and eight of stress indices including stress tolerance index (sti), stress tolerance (tol), stress susceptibility index (ssi), mean prod...
The present study was undertaken in order to evaluate nativedesiccation tolerance and its mechanism in wheat seedlings of different genotypes. At the first step, drought stress was applied by using different concentrations of poly ethylene glycol (PEG) and mannitol. Since the fact that these compounds (even in high concentrations) were not able to produce sever water stress, the experiment was ...
Introduction: Different mechanisms are involved in stress induced analgesia (SIA) and hyperalgesia (SIH). Repeated stress induces development of tolerance to SIA. The role of HPA axis and Gs signaling pathway in these effects are investigated in the current study. Methods: Forced swim stress (5 min/day) in water (20±1 ºC) was employed to adult male Wistar rats (200-250 g). The nociceptive t...
This study was conducted at Research Farm of Isfahan University of Technology to evaluate drought tolerance potential of 23 F2:4 wheat lines derived from the cross of Virmarin (susceptible line) and Sardari (tolerant line). A randomized complete block design with three replications was used in each irrigation treatment (i.e. irrigation after 70±3 and 120±3 mm evaporation from class A pan for ...
Drought stress is considered as one of the most important constraints to the crop production, including medicinal plants in many arid and semi-arid regions. This study was carried out to determine the most effective indices for drought tolerance and identification of tolerance genotypes under drought conditions in N. sativa. For this purpose, 36 genotypes of N. sativa were tested as a split plo...
The present study was conducted to investigate the genetic diversity and evaluate the drought tolerance indices on 16 genotypes of faba been based on split plot design with three replications in Agricultural Research Center of Borujerd. Irrigation regimes as the including normal and drought stress levels and genotypes were considered as the main and sub plot,respectively. Analysis of variance f...
