Response of three wheat genotypes grown under saline medium to low\high potassium levels

A water culture experiment was conducted, to study the response of three wheat genotypes (Sarsabz, Kiran-95 and Pasban-90) to low and high potassium levels, (0.01 and 10 mM KCl) grown under two salinity concentrations (50 mM and 150 mM, NaCl). The results showed that the presence of sufficient potas...

Description
Summary:A water culture experiment was conducted, to study the response of three wheat genotypes (Sarsabz, Kiran-95 and Pasban-90) to low and high potassium levels, (0.01 and 10 mM KCl) grown under two salinity concentrations (50 mM and 150 mM, NaCl). The results showed that the presence of sufficient potassium in the growth medium was found to bring good effects on plant growth. The data showed that shoot length of Kiran-95 growing under two salinities and associated with low and high potassium was quite satisfactory followed by Sarsabz and Pasban-90. Ionic content in plant shoots also varied with the increase in salinity levels of the medium. Potassium content in plant shoot was strongly regulated by Na+ ions, showing gradually decrease in K with the increase in Na accumulation in shoot. Under high salinities Kiran-95 had maximum K content in both low/high K supply, followed by Sarsabz and Pasban-90. This ability of Kiran-95 to maintain optimum K level may be the reason of its better survival
