In shallow rainfed rice agro-ecosystems, drought stress can occur at any growth stage and can cause a significant yield reduction. During recent years, some rice varieties possessing tolerance of reproductive-stage drought stress have recently been developed. Tolerance of vegetative-stage drought stress is also required to improve rice productivity in drought-prone regions. In this study, we ev...

Background & aim: Occupational exposures can cause problems such as reproductive system disorders; however, the effects of some exposures, such as psychological stress, have not been investigated yet. This study aims to investigate the effects of women’s psychological stress on obstetric disorders. Methods:This historical cohort study was conducted on 1400 working women in Mashhad, Iran. Data ...

Current studies have not conclusively demonstrated an objective and consistent marker of an aberrant stress response; an effect of such a stress response on reproductive outcome; or a benefit of counseling on reproductive outcome in such patients.

in order to evaluate the effect of salicylic acid on yield and yield components of bean genotypes under water deficit stress, an experiment was carried out as a factorial split plot design with three replications in research farm bu ali-sina university (hamadan, iran) during 2009. stress levels: consist of vegetative water stress, reproduction water stress and without water stress (control) and...

the response of plants to drought stress depends on several factors including the plant developmental stage and the length and severity of the stress applied. common bean (phaseolus vulgaris l.) is the most important pulse crop that is cultivated worldwide for human consumption. understanding of the mechanisms responsible for its response to drought is, therefore, essential. an increasing numbe...
