Salinity is one of the most important ecological stresses which have undesirable effects on seed germination. This study was carried out to evaluate the germination of three species of lawn (Poa pratensis, Lolium perenne, Cynodon dactylon) seeds under salinity stress. The effect of different treatments (Gibberellins 50 mgl-1, 2% CaCl2 and hydroprimig in 24 hours) was evaluated on total germinat...

Boron (B) is essential to growth at low concentrations and limits growth and yield when in excess. Little is known regarding plant response to excess B and salinity occurring simultaneously. In this study, two models of Leibig-Sprengel (LS) and Mitscherlich-Baule (MB), originally proposed to explain plant response to nutrients only, were modified to evaluate canola yield response to combined le...

The culture of Litopenaeus vannamei in inland low salinity waters is currently being practiced in various countries around the world. These environments are often deficient in key ions essential for normal physiological function, including potassium (K) and magnesium (Mg). Farmers have sometimes been able to counteract ionic deficiencies in the water profile by adding mineral salts containing s...

 In this study, the effects of salinity on the hematological parameters in Mesopotamichthys sharpeyi were investigated within 21 days. One hundred and twenty fish weighing 300-350g were divided randomly to four treatments of urban water and following 3 salinities: 4, 8 and 12 g/lit and blood samples were taken in following days of experiment: 1th, 3th, 7th, 14th and 21th.Hematological parameter...

In a series of studies conducted in Malawi to determine the effects of different salinity concentrations on survival, growth, feed conversion, reproduction, and whole-body composition of five taxonomic groups of tilapia—Oreochromis shiranus chilwae (Lake Chilwa strain), O. shiranus chilwae (Bunda College strain), O. karongae, O. shiranus shiranus, and Tilapia rendalli—it was observed that the f...

Salinity of water irrigation and soil are of the major factors affecting plant growth and productivity worldwide. In this research the effects of salicylic acid on some morpho-physiological and biochemical characteristics of walnut (Juglans regia) seedlings under salinity stress condition were studied. The experiment was a two-factor factorial experiment arranged in completely randomized design...
