Development of drought-tolerant cultivars is hampered by a lack of effective selectioncriteria. In this research, response of 36 genotypes of rapeseed from seven species of Brassicaincluding B. napus, B. rapa, B. juncea, B. carinata, B. oleracea, B. nigra and B. fruticulosa wasassessed under three moisture levels (no stress, mild stress and intense stress) in the field during2011-2012. Five dro...

This study was conducted to determine drought tolerance genotypes with superiority in different stressed environments. To screening quantitative indices of drought tolerance, genotypes of safflower (Carthamus tinctorius L.) were tested in a complete randomized block design with three replications under two different water regimes (irrigated and rainfed). Significant positive correlatio...

  This study was conducted at Research Farm of Isfahan University of Technology to evaluate drought tolerance potential of 23 F2:4 wheat lines derived from the cross of Virmarin (susceptible line) and Sardari (tolerant line). A randomized complete block design with three replications was used in each irrigation treatment (i.e. irrigation after 70±3 and 120±3 mm evaporation from class A pan for ...

Drought is one of the major environmental stresses that adversely affect crop growth and productivity worldwide. For evaluation of drought stress on grain yield, yield components and drought tolerance indices, 20 genotype of rapeseed (Brassica napus L.) was studied in an experiment based on a randomized complete blocks design with three replications in two different conditions (stress and non-s...

In order to study the genetic diversity of 75 Iranian rice genotypes (45 Iranian land race, 25 improved cultivars, and 5 exotic cultivars) with respect to their salinity tolerance at seedling stage and to determine tolerance indices, based on biomass, genotypic code and Na+/K+ ratio a factorial experiment in randomized complete block design with three replications was conducted under control an...

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...

Rigorous and precise formulation of tolerancing and dimensioning plays an important role in tolerance evaluation using CMMs. In this paper, we rst present a uniied geometric formulation of form tolerances using an extended least-squares E-LSQ approach. Then, using properties of connguration space of symmetric features an iterative algorithm is developed to solve the E-LSQ problem. Simulation re...

in order to identify and selection salt tolerant hybrids based on tolerance indices, 17 sugar beet three-way cross hybrids produced by crosses between 17 salinity improved s1 pollinators and a cytoplasmic male sterile (cms) single cross as female, along with three control genotypes were grown in 2007 in rudasht station (isfahan) under saline (12 ds/m and 8 ds/m for water and soil) and non-salin...
