The importance of different species of savory is due to having phenolic compounds such as carvacrol and thymol in the essential oil and rosmarinic acid in the extract, having strong antioxidant and antimicrobial effects. This study was conducted on five ecotypes of Satureja rechingeri in in vitro and in vivo experiments. After determining the best shooting and rooting medium, micropropagation w...

At percent, Zn stress tolerance using novel genetic resources is an important mitigation strategy for plant breeding. In this study, thirty-five durum wheat genotypes with different growth habits were evaluated under normal (non-stress) and Zn deficient stress during the 2014-15 cropping season. A total of ten Zn stress tolerance indices including stress tolerance index (STI), relative zinc-def...

Extended Abstract Introduction and Objective: Drought stress as one of the most important abiotic stress is the main limiting factor of oilseed rape cultivation in arid and semi-arid climates. Therefore, the identification of drought tolerant genotypes is the essential programs in these regions. One of the appropriate methods to identify drought tolerant genotypes is the use of stress toleranc...

the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...

all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...

Drought stress is the major problem in arid and semi-arid regions of the world. Investigating the response of different cultivars of crop plants to drought stress can help to select the tolerant ones for agriculture in arid lands. In this study, a greenhouse experiment was conducted as a factorial experiment based on completely randomized design with two common bean cultivars (Phaseolus vulgari...

The amplified fragment length polymorphism (AFLP) assay is an efficient method for the identification of molecular markers, useful in the improvement of numerous crop species. Bulked Segregant Analysis (BSA) was used to identify AFLP markers associated with water-stress tolerance in barley, as this would permit rapid selection of water-stress tolerant genotypes in breeding programs. AFLP marker...
