abstract to study the effect of water stress in rapeseed cultivars at the seedling stage, 10 rapeseed cultivars were evaluated at three irrigation levels [normal irrigation (control) and irrigation after depletion of 60 and 85% of available soil water]. analysis of variance showed considerable variation among cultivars. water stress reduced all of the studied morphological characteristics, espe...
vicia sativa l., an annual winter growing leguminous plant, is a valuable source of protein and minerals for cattle. drought is one of the key stress factors that influence plant growth and development. in order to investigate common vetch physiological and molecular responses under normal irrigation (n) and two levels of drought stress [s1= 30% and s2= 10% field capacity (fc)], a greenhouse exp...
investigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
to evaluate the effects of water deficit stress in barley germplasm collection of national gene bank ofiran, 25 genotypes collected from arid and semi arid provinces of iran and 3 sample cultivars werestudied in two environments including: non-stressed and water deficit stress. agronomical, phenologicaland morphological traits were measured. stress indices were calculated to determine tolerant ...
this study was carried out to investigate the effects of integrative vs. instrumental motivation, learning strategy use and gender on iranian efl learners. to this end, 120 efl learners both male and female majoring in english language and literature at shiraz university participated in the study. in order to conduct this study three instruments were used: oxford quick placement test, motivatio...
introduction nowadays, salinity is one of the limiting factors for crop production in arid and semi-arid regions. on the other hand, sorghum (sorghum bicolor l.) is a self-pollinated and short-day plant, which partly has been adapted to salinity and water stress conditions; also play an important role in humans, livestock and poultry nourishments. all studies have showed the positive effects of...
Quantitative traits and the response of 20 genotypes of soybean to water deficit stress were evaluated at Agricultural Research Station of Gorgan in 2010 and 2011. Therefore, 3 separate experiments were conducted, each experiment as randomized complete block design, in 3 replications. In the first experiment, all soybean genotypes were irrigated based on 50 mm evaporation from evaporation pan...
the thesis has been arranged into five chapters and mainly concerned with the baer-invariant of groups which is the generalization of the schur-multiplier with respect to the variety of groups. chapter one is devoted to collect some notation and background information which are needed in the next chapters. its also contains some important statements which will be generalized in this thesis. cha...
this study investigated the effect of prior knowledge on the listening comprehension performance of fl learners. twenty students, male and female, drawn from the two intact groups of the senior and junior english language and literature majors were chosen as the participants of this study . the two groups were then randomly assigned into the experimental and control group. the experimental gr...
Drought is an important factor limiting crop production in arid and semi-arid conditions. Drought indices which provide a measure of drought based on yield loss under drought condition in comparison to normal condition was used for screening drought-tolerant genotypes. This study was conducted to determine drought tolerant genotypes with high yield in stress and non-stress conditions. Ten barle...
