This experiment was conducted to evaluate drought tolerance of different safflower genotypes as a split- plot experiment based on a complete block design with three replications. The main plot was irrigation at three levels on the basis of 70, 120 and 170 mm cumulative evaporation from Class A pan and ten different genotypes of the safflower were considered as subplots. Results of analysis of v...

In order to examine the effects of plant density on the morohological traits, yield and essential oil of peppermint, an experiment was conduced in Agricultural College of Tabriz University during 2005 and 2006. The treatments included four plant density levels ( 8,12 ,16,20 plants.m-2) with three replications. The treatments were based on a split plot design in time and result analysis of compo...

Drought tension and iron fertilizer play an important role in determining the grain yield and quality of oil seed products. Therefore, a split plot-factorial experiment based on randomized complete blocks design with three replications was conducted to investigate the effect of foliar application of iron nano-chelate and folic acid on some quantitative and qualitative traits of two sesame culti...

we have two part in this thesis, at first: the interaction of native calf thymus dna (ct-dna) with two anthraquinones including quinizarin (1,4- dihydroxy anthraquinone) and danthron (1,8- dihydroxy anthraquinone) in a mixture of 0.04 m brittone-robinson buffer and 50% of ethanol were studied at physiological ph by uv-vis absorption, florescence, circular dichroism spectroscopic methods, viscos...
