considering forage grass species, germination is one of the important stagesconcerning the growing stage that is often influenced by environmental stresses,particularly salinity and drought stresses. thus, this study aims to assess the effects ofsalinity and drought stresses on germination characteristics and seedling growth of desertwheatgrass, agropyron desertorum (fisch. ex link) schult. in ...

this study investigates the effects of garlic extract on salinity and ph stress resistance of white leg shrimp post larvae (0.1±0.01 g). the experiment was carried out on the basis of completely random model with 5 dietary treatments which include 0 (control treatment), 1cc (treatment 1), 2cc (treatment 2), 4cc (treatment 3) and 8cc (treatment 4) per 100g food in triplicate. 1500 shrimps were r...

considering the extent of salinity in soils of iran, abiotic stresses such as salinity are serious threat to agricultural production, yield and essential oil of medicinal plants. recognition of threshold for salt tolerance and determining the slope of yield loss in medicinal plants has an important role in the selection of suitable lands for their cultivation. the effect of salinity stress on s...

Expert assessments for crop and range productivity of very-large arid and semiarid areas worldwide are ever more in demand and these studies require greater sensitivity in delineating the different grades or levels of soil salinity. In conjunction with field study in arid southeastern Oregon, we assess the merit of adding decision-tree analysis (DTA) to a commonly used remote-sensing method. Ra...

Salinity tolerance of four grape genotypes [GharaUzum, Hosseini, AghUzum and Keshmeshi] was studied under various salinity levels (25, 50 and 100 mM NaCl). As a result, growth indices were significantly (P<0.05) reduced by salinity, whereas Cl- and Na+ contents in the plant parts were increased. Cl- accumulation exceeded than that of Na+ in all treatments. Among the genotypes studied, GharaUzum...

Salinisation is a global threat to freshwater habitats and predicted worsen with climate change. Increases in salinity can result substantial modification of biotic communities through both direct toxic effects indirect such as altering prey resources, competitive interactions, predator abundances, facilitating the spread invasive species. Traditional techniques determine salinity, point sampli...
