salinity and drought are two major abiotic stresses that affect rice (oryza sativa l.) production in worldwide. salt and drought tolerance and high seedling vigor of rice is one of the important traits in the establishment of seedling in direct planting system and saline and drought environments. in this research, the mapping population of f2:4 families derived from the cross between local vari...

salinity tolerance is a genetically and physiologically complex trait, controlled by quantitative trait loci (qtls). in order to map the qtls associated with agronomic and physiological traits, 149 doubled haploid lines derived from a cross between clipper (salt susceptible) and sahara 3771 (salt tolerant) barley genotypes were evaluated under natural saline-stress and non-stress conditions usi...

burnout is a response to the chronic work stress which is prevalent mostly among the people who do people job, like teaching. the purpose of this study was to develop a valid and reliable instrument that can measure burnout in foreign language teachers. although some widely used instruments were developed before which measured burnout in teachers, a specific instrument which include specific sy...

salinity stress is a major limitation in wheat production. the lack of economically viable methods for screening salinity tolerance in field is an obstacle to breeders. in this study a population of 254 recombinant inbred lines (rils), derived from a cross between roshan × sabalan was assessed in glasshouse during the seedling phase in order to identify quantitative trait loci (qtls) for salini...

abstract birbery and corruption and other criminal and as such is one of social phenomena , and i can firmly say that society is protected and safe from harm , this is criminal . eache community is familiar with these crimes and the crime associated ( direct or indirect ) with the political economic , social , and cultural beliefs and religious issues , especially with the community . admitted...

Salinity stress is one of the most widespread soil problems next to drought, in rice growing areas. ReducingSodium (Na+), while maintaining Potassium (K+) uptake in rice are traits that would aid in salinity tolerance.Therefore, the identification of quantitative trait loci (QTLs) associated with those for Na+ and K+uptake, will enable breeders to use marker-assisted selection...

mapping the QTLs of agronomic and physiological traits, 149 double haploid (DH) lines from a cross between an Australian cultivar, Clipper (salt susceptible), and an Algerian landrace, Sahara3771 (salt tolerant), were evaluated under natural saline (Yazd Station, ECsoil=10-12.8 ds/m and ECwater= 9-10 ds/m) and normal (Karaj Station, ECsoil and ECwater ~2-2.5 ds/m) environments. There were remar...

salinity stress is one of the most important abiotic stresses which threaten plants. in order to study the effect of salinity stress on yield and yield components of sunflower and also genetic analysis of these traits in relation with salt tolerance, a factorial experiment based on a completely randomized design with three replications was conducted. pots were arranged outside the greenhouse in...

in order to assess the genetic variability for seed germination parameters under salt stress in sunflower and corresponding qtl locations, an experiment was conducted using a population of 80 recombinant inbred lines obtained from a cross between pac2 and rha266. the experiment was arranged under a randomized complete block design with three replications in control and saline conditions. severa...

three medium magnitude events happened inside the transitional border of south alborz and central iran; namely kahak-qom 2007/06/18 event with ml 5.6, zanjan 2008/05/27 event with ml 5.3 and aradan-garmsar 2007/11/19 event with ml 5.1. this provides us the opportunity to compute focal mechanism and stress drop of the events and compare them with those events happened within the alborz range.
