the genus eremostachys (lamiaceae), consists of about 60 species which 15 species of eremostachys grow wildly in the north-west of iran. the rhizomes and roots of e. laciniata have traditionally been used as a local analgesic and for the treatment of rheumatic diseases and pain in the feet. this experiment was conducted in the north-west of iran in 2012-2013, to evaluate morphological diversity...

purpose:     methods:     results:     conclusion:

introduction climate change happens due to abnormal changes of climate within the earth’s atmosphere and their consequences. one of the most significant effects of climate change is the irreversible damage to some floral species and forest ecosystems. tree species reflect the impact of climate changes on their ring width. generally, tree rings vary in size each year depending upon the environme...

the application of organic sorbents for removing heavy metal from water, replacing expensive sorbents, is particularly appropriate for developing countries. to investigate the efficiency of some organic sorbents in removing of cd2+ from aqueous solution, an experiment was conducted with three organic sorbents (sunflower stalks, apple and grapevine pruning residues) and 11 initial concentration ...

in order to investigate the impact of government policies on supply, cropping area and yield of sugar beet during 1981-2003, nominal rate of protection (nrp) was applied as a variable to persuade government’s policies in this study. results showed that despite of its negative impacts on cropping area, the nrp has positive effects on supply and yield of sugar beet iniran. moreover, real price of...

drought resistance is a very important characteristic needed for plant survival especially at germination stage, in arid and semi-arid lands. phosphatase enzymes are widely found in plants. these enzymes are responsible for dephosphorylation of organic phosphate and altering it to mineral phosphate. germination experiments were conducted in two bread wheat cultivars (sardari and alvand) under s...

evaluation of changes present in soil and water resources due to operation implement of floodwater spreading is necessary to assess their positive or negative resultant effect. rate of the internal sediment to diversion spreader channels, surface sedimentation and aggregation of the spreading field depth are most important effective attributes on the yield of floodwater spreading systems. these...

aim: the aims of this study were to characterize iranian shigella sonnei strains isolated from pediatric cases and evaluate the utility of multilocus variable-number tandem-repeat (vntr) analysis (mlva) for genotyping of local s. sonnei strains. background: s. sonnei has become the dominant species in certain parts of iran. although pfge is still a gold standard for genotyping and source tracki...

drought tolerances of 55 indigenous strains of pseudomonas fluorescens were evaluated. to assess the tolerance rate of the strains to various levels of water deficit, their growth rate in nb medium containing concentrations of 40.587, 438.838 and 548.838 g of polyethylene glycol 6000 per liter of medium were utilized. water potentials of aforesaid levels were estimated as 0, - 10, - 20 and -30 ...
