in order to study genetic variation and relationship between traits, 615 accessions of local bread wheat from wheat collection of national plant gene bank of iran were evaluated. seeds of the accessions were planted in 2.5 meter long rows in an observatory design and 17 agro-morphological traits were measured. grain yield of 5 spikes, number of tillers and number of seeds per spike were of high...
this experiment was conducted to investigate and evaluate the phenotypic and genotypic diversity of a population including of 94 doubled-haploids lines, their parents and five iranian local bread wheat (triticum aestivum l.) cultivars. thirteen agronomic and morphologic traits were recorded including; grain yield per unit area, harvest index, spike length, seed number per spike, spikelet densit...
in the first part of this thesis we explored wetting and its dynamics for small droplets. first, we showed how a simple feature of water droplets on a surface, i.e. laplace pressure, can be exploited to build a micropump. we investigated capillary pumping in microchannels both experimentally and numerically. putting two droplets of different sizes at the in/outlet of a microchannel, will ge...
to investigate the yield and agronomic traits of winter bread wheat genotypes in irrigating condition and also to determine the relationship of these traits with grain yield, 15 advanced genotypes of wheat along with three conventional cultivars where studied using randomized complete block design in three replications in 2010 growing season at kheyr-abad agricultural research station. the anal...
in order to determine the effects of applied phosphate bio-fertilizer on yield and morphological traits of wheat, a research was conducted in sari agricultural sciences and natural resources university during 2008-2010. a factorial experiment was performed based on randomized complete block design with four replications. the first factor consists of two levels of phosphate bio-fertilizer (0 and...
abstract previous researches have shown success of growth hormones usage on flower production increase, pod and prevention of abscission of them in some of the pulses. two tests were done, in order to find out the effects of growth hormones to on flower production increase, pod and chick pea yield composites in farmer conditions (2010-11) and green house conditions as factorial on the proje...
this study was conducted to evaluate genetic diversity of durum wheat cultivars using multivariate analyses on agronomic and morphological traits. thirty genotypes were planted in a randomized complete block design with three replications in 2003. agronomic and morphological characteristics including days to flowering, days to pollination, days to maturity, plant height, spike length, grain wei...
one of the most commonly used techniques to reduce the corrosion rate of rebar in concrete is addition substances named corrosion inhibitors into the concrete. corrosion inhibitor is chemical compounds that were added to concrete to prevent corrosion of steel in concrete. sodium nitrate is a type of anodic inhibitors that this study investigatesthe effect of this inhibitor on the properties of ...
Abstract In order to study the inheritance of grain yield and its components in bread wheat, two cultivars, Karchyya(drought and salinity tolerant) and Gaspard (sensitive to drought and salinity stress) were crossed.Parents together with F1, F2, F3, BC1and BC2 generations were evaluated using a randomized complete block design with three replications in 2008-2009 growing season.Grain weight per...
For identification of correlations and relations among different traits in bread wheat, 30 genotypes were investigated based on a split plot experiment in the form of randomized complete block design with three replications under normal and moisture stress conditions during the 2016-2017 crop season. The results of the analysis of variance showed that the effect of genotypes was significant for...
