in order to evaluate the best drought resistance indices in sugar beetgenotypes, an experiment was conducted in 2002 using a split- plot design within randomized complete block design with three replications at the research farm, shiraz-zarghan. the main plots consisted of three irrigated regimes: non stress, 75% (mid stress) and 50% (intense stress) non stress and the ten genotypes as the sub ...

assessment of soil quality is one of the most useful tools for evaluation the soil management condition and different land uses. quantity indices of soil quality are most suitable methods for determination and comparison of soils quality. in this study soil quality indices and selection methods of effective soil properties were compared for evaluating the soil quality in different land uses. se...

background: the critical role of interleukin-7 (il-7) in homeostatic proliferation and t cell survival has made it a promising cytokine for the treatment of various clinical conditions, especially those associated with lymphopenia. methods: in the present study we expressed recombinant human interleukin-7 (rhil-7) in chinese hamster ovary (cho)-k1 cells. cho-k1 cells were stably transfected wit...

background: radium-226 (226ra) is a product of the 238u radionuclide decay series that significantly incorporated into the human body through water intake. it can also potentially cause a series of health problems including cancers of the digestive system. radium-226 (226ra) is a product of the 238u radionuclide decay series that significantly incorporated into the human body through water inta...

in order to determine the best traits related to indirect increasing of grain yield, five wheat genotypes (zagros, tajan, durum cul., kohdasht and n-81-18 line) were evaluated by using randomized complete block design (rcbd) with 4 replications in research field of gorgan university of agricultural sciences and natural recourses. the studied traits included leaf area index (lai), crop growth ra...

plant growth-promoting rhizobacteria (pgpr) is an alternative to chemical pesticides against harmful microorganisms especially soil-borne diseases. rhizoctonia solani is one of the most important soil-borne fungal pathogens that causes serious damages to important crops. in this study, to screen successful pseudomonas bacterial isolates, the inhibition of pathogen growth was evaluated in-vitro....

rambutan tree (nepheliumlappaceum l.) is an important but a lesser known fruit tree in ghana and has several nutritional and medicinal uses. efforts to establish plantation of rambutan in ghana to ensure its sustainable use is challenged with unavailable planting materials because the seeds are recalcitrant in nature, loses viability easily when exposed to dryness. seeds are therefore sown dire...

to study the effects of drought stress and foliar application with salicylic acid on yield andit’s components and percentage of essential oil of nigella sativa l., a field experiment was conducted as split plot based on randomized complete block design with three replications at research farm of shahid bahonar university of kerman during growing season of 2013- 2014. the main factor was drought...
