Soil salinity affects a large part of the region in Iran. Salinity covers 12.5% oftotal area of the country. Priming of seeds in sodium chloride and water (hydro-priming)has been reported to be a simple technique for enhancing the seedling establishment andgermination performance in the seeds of many crops and small seeded grasses under thestress conditions. Therefore, the aim of this research ...

Effects of dietary synbiotics on growth performance, survival, stress resistance, body composition and immune response in the Caspian roach (Rutilus rutilus) were evaluated. Fish with an initial average weight of 4.14±0.25 g were randomly distributed into tanks (50 fish per tank) and triplicate groups were fed a control diet or diets containing 1 g kg-1 and 2 g kg-1 synbiotics. After an ...

The objective of present study was to evaluate the response of the mung bean seeds of ‘Sonali B1’ variety primed with chitosan in four different concentrations (0, 0.1%, 0.2% and 0.5%) under salinity stress of five different concentrations (i.e., 0, 4, 6, 8 and 12 dS*mm) and halotolerance pattern by applying Celite as matrix at three different moisture levels (5%, 10% and 20%). Improved germina...

BACKGROUND: Among the environmental stresses soil salinity is a widespread environmental problem that has been found to affect more than 77 million hectares or 5% of the cultivable land of the universe. Potassium has a positive role in plant growth under saline conditions, because this element plays an essential role in photosynthesis, osmo regulatory adaptations of plant to wa...

The effects of temperature and salinity stress on hemato-immunological factors in juvenile Labeo rohita fed normal or elevated levels of tryptophan were studied. Fish were fed diets with 0.35% (control), 0.7%, or 1.4% tryptophan for 60 days, then exposed to temperature and/or salinity stress for the next 30 days with the same feeding regime. The specific growth rate (SGR) was significantly redu...

abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...
