the experiment was aimed at investigating the effects of defoliation (i. e. amanipulation of source size) at different times and with different intensities on yield, grain protein content and remobilization of dry matter from shoot to grain under various levels of soil moisture and nitrogen in winter wheat. two separate field experiments were conducted simultaneously under water stress vs irrig...
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...
The pinning effect of small incoherent particles on grain growth in two-dimensional polycrystalline systems has been simulated using a phase field model. Simulations were performed for different sizes and area fractions of the second-phase particles and for two types of initial microstructure and different initial grain sizes. The grain size distribution and the number of particles located at g...
The use of high yielding and resistant to drought stress cultivars in crops is one of the proper way to incorporation other water deficit management methods. This study in order to evaluate grain yield and morphological traits, an experiment was conducted with 100 genotypes of durum wheat which were planted based on lattice design with three replications under normal and drought stress conditio...
The half-integer quantum Hall effect (QHE) is often suppressed in graphene grown by chemical vapor deposition on metals. The reason behind the suppression is unclear, and we hypothesize that it might be connected to extended defects in the material. In this paper we present results for the quantum Hall effect in graphene with [0001] tilt grain boundaries connecting opposite sides of Hall bar de...
In order to identify the most important traits affecting yield in maize inbred lines and hybrids, an experiment was conducted in Shushtar City in 2009 and 2010 years. Fifteen inbred lines in 2009 and 28 hybrids in 2010 studied in two planting dates, 6 July (to coincide heat stress with pollination time and grain filling) and 27 July (normal condition) using a randomized complete block design wi...
Field experiment was conducted at KPK Agricultural University, Peshawar, Pakistan to find out the effect of planting methods on the yield and yield components of maize varieties. Analysis of the data revealed that planting methods had a significant effect on days to tasseling, days to silking, plant height, number of plants ha at harvest, thousand grain weight, grain yield, biological yield, fr...
in order to evaluate the relationship between morphological characters in rice lines two populations at f3 generation were grown in research field of agricultural sciences and natural resource university, sari, iran, during 2012. statistical analysis on important agronomic traits showed that maximum standard deviation belonged to total grain number followed by filled grains per panicle and grai...
there are different methods used for threshing of grain crops. usual threshers operate based on the impact force (in threshing unit) that may damage the grains. in another method named axial-flow, grain damage is less so these types of the harvesting machines are being used more than before. in this study one of the common rice threshers (model t30) locally made in ashtad company was modified t...
The dynamics of dislocation assemblies in deforming crystals indicates the emergence of collective phenomena, intermittent fluctuations and strain avalanches. In polycrystalline materials, the understanding of plastic deformation mechanisms depends on grasping the role of grain boundaries on dislocation motion. Here the interaction of dislocations and elastic, lowangle grain boundaries is studi...
