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...
in order to increase drought tolerance in bread wheat, an appropriate breeding program based on inheritance of drought tolerance is recommended. in the present study, nine bread wheat cultivars and their f2 progenies were evaluated in a randomized complete block design under normal and drought stress conditions. nine sensitivity/tolerance indices were calculated for studied genotypes and stress...
A complete diallel cross of nine cotton genotypes (Gossypium hirsutum L. & Gossypium barbadense L.) viz Delinter, Sindose-80, Omoumi, Bulgare-539, Termez-14, Red leaf (Native species), B-557, Brown fiber and Siokra-324 having diverse genetic origins was conducted over two years to determine the potential for the improvement of yield, its components, oil and fiber qual...
over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
The study of the genetic structure controlling agronomic traits is one of the preconditions for selecting the appropriate breeding method. In order to analyze genetic of some agronomic traits of bread wheat using generation mean analysis, parents and different generations resulting from the cross of Marvdasht × MV-17 wheat cultivars were assessed in a randomized complete block design with three...
abstract governing was disorganized for years, when mongols attached to iran and it caused to clearing way for interference of mongols princes. dispatching of holaku to the west culminated in establishing iilkhanan government. holakus activities in destruction of abbaasis government and activities which shows his staying in iran, made force oulus juji to comparison against iilkhanis gover...
Extended Abstract Introduction and Objective: Wheat is one of the most important crops in the world that plays a key role in ensuring food security. In wheat breeding programs, selection of genotypes with desirable agronomic traits and high yield potential have always been the goal of plant breeders. Increasing the selection efficiency for grain yield depends on genetic knowledge from morpholo...
pyramiding genes related to grain quality and resistance through marker assisted selection (mas) is an important approach in rice breeding programs. marker-assisted selection can be used for monitoring the presence or absence of these genes in breeding populations and can be combined with conventional breeding approaches. this study is a part of cultivar development program in iran through inte...
cultural iran is a scope that is more extended than the political territories of iran as a political unit. this concept means that cultural geography(mehdi moghanlo-1383-1) of iran is greater than its political geography which, according to history, has a long history extending west-east from kandahar to the euphrates and north-south from the persian gulf to the caucasus including transoxiana a...
