Poa genus has a high value for grazing and forage conservation concerning thelivestock. In order to study the impacts of cold temperature and Growing Degree Days(GDD) on seedling morphological trait and phonological development of two speciesinvolving Poa pratensis and Poa trivialis, this research was conducted in laboratory andgreenhouse and outdoor of Research Institute of Forest and Rangelan...

Drought and salinity are major abiotic stresses to crop production. Here, we show that overexpression of stress responsive gene SNAC1 (STRESS-RESPONSIVE NAC 1) significantly enhances drought resistance in transgenic rice (22-34% higher seed setting than control) in the field under severe drought stress conditions at the reproductive stage while showing no phenotypic changes or yield penalty. Th...

in order to study of nitrogen absorb and use efficiency of wheat (triticum aestivum) and wild oat (avena fatua) at vegetative growth stage, a factorial experiment was conducted based on completely randomized block design with three replications in research greenhouse of faculty of agriculture, at ferdowsi university of mashhad in 2008. the first factor was competition between wild oat (densitie...

The occ urrence of water sources with high concentrations salts is a common problem in the semi-arid region ofnorth-eastern Brazil. search for management strategies that can minimize effect salt stress on crops therefore extremelyimportant. As such, this study aimed to evaluate gas exchange and production yellow passion fruit ‘BRS GA1’as function ofirrigation using brackish doses potassium. res...
