Adverse Effects of Salinity on Citrus
Due to the rapid expansion of irrigated agriculture, efficient use of the limited water resources in arid and semi-arid regions is becoming more and more vital. However, water salinity is a major problem due to its negative influence on the yields of many crops. It reduces citrus trees’ growth and causes physiological disorders. Salt-stress lowers net CO2 assimilation, stomatal conductance, and...
متن کاملInitial salinity tolerance and ion-osmotic parameters in juvenile Russian Sturgeon, Acipenser gueldenstaedtii, Brandt, 1833
The salinity tolerance, hematological and hydromineral regulation capabilities of juvenile Russian sturgeon (Acipenser gueldenstaedtii) were investigated in different ages and sizes in freshwater (FW: 0.05) but differed in experimental media (p < 0.05). Signifi cant differences were observed between the levels of plasma ion concentrations in different media (p < 0.01). Plasma Na+, K+ and Ca+2...
متن کاملInitial salinity tolerance and ion-osmotic parameters in juvenile Russian Sturgeon, Acipenser gueldenstaedtii, Brandt, 1833
The salinity tolerance, hematological and hydromineral regulation capabilities of juvenile Russian sturgeon (Acipenser gueldenstaedtii) were investigated in different ages and sizes in freshwater (FW: <0.5‰), estuary water (EW: 9.5‰) and Caspian Sea water (CSW: 12.5‰). The fish were directly transferred from FW to EW and CSW. The possible repercussions of ion-osmoregulatory processes on some ...
متن کاملThe effects of salinity and osmotic stress on barley germination rate: sodium as an osmotic regulator.
BACKGROUND AND AIMS Seed germination is negatively affected by salinity, which is thought to be due to both osmotic and ion-toxicity effects. We hypothesize that salt is absorbed by seeds, allowing them to generate additional osmotic potential, and to germinate in conditions under which they would otherwise not be able to germinate. METHODS Seeds of barley, Hordeum vulgare, were germinated in...
متن کاملOsmotic and specific ion effects on the germination of Prosopis strombulifera.
BACKGROUND AND AIMS Salinity can affect germination of seeds either by creating osmotic potentials that prevent water uptake or by toxic effects of specific ions. Most studies have only used monosaline solutions, although these limit the extent to which one can interpret the results or relate them to field conditions. The aim of this work was to evaluate the germination of Prosopis strombulifer...
