Agropyron is one of the most resistant plants to biotic and abiotic stresses. It plays an important role in forage yield in rangelands. Genetic variability based on different markers is the important step in crop improvement. In order to evaluate the genetic variation of different Agropyron species based on morphological and chemical traits, this experiment was carried out in the Agriculture an...

Studying the genetic structure of crops, including wheat, has always been one of the research priorities to increase the efficiency of breeding methods. In order to genetic analysis of some agronomic traits of bread wheat using generation mean analysis (GMA), all produced generations along with relevant parents of the two populations (Marvdasht × Rasoul and Marvdasht × Shahpasand) were evaluate...

Climate Change is a serious risk to crops as it harnesses the survival of plants and major cause for drought stress in many areas world including Pakistan. Most cultivated area Pakistan vulnerable conditions brought about by climate change, leading fewer productive harvests. Wheat Pakistan's staple food crop, but needs be enhanced developed more tolerant conditions. We all know that future wate...

This paper focuses on the automatic extraction of Arabic Named Entities (NEs) from the Arabic Wikipedia (AWP), their automatic attachment to Arabic WordNet (AWN) and their automatic link to Princeton's English WordNet (PWN). We briefly report on the current status of AWN, focusing on its rather limited NE coverage. Our proposal of automatic extension is then presented, applied and evaluated. Ke...

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...

drought stress is one of the most important environmental stresses that affect yield of bread wheat strongly. considering that the yield achieved with the interaction of a large number of plant traits and environment, so the morphological and agronomical traits, can serve as selection criteria under environmental conditions. by genetic analysis and estimation of inheritance and mode of gene act...

to investigate the influence of salinity and calcium (ca) on some properties of plantago ovata, a pot factorialexperiment based on randomized complete block design with three replicates was conducted in jiroft, south of kermanprovince, iran. three salinity levels of 0, 100 and 200 mm nacl and ca levels of 0, 5 and 10 mm calcium nitrate wereapplied as the first and second factors, respectively. ...

AWN is a process algebra developed for modelling and analysing protocols for Mobile Ad hoc Networks (MANETs) and Wireless Mesh Networks (WMNs) [2, §4]. AWN models comprise five distinct layers: sequential processes, local parallel compositions, nodes, partial networks, and complete networks. This development mechanises the original operational semantics of AWN and introduces a variant ‘open’ op...
