Bot. VL - 50 IS - 4 SE - Short Communications DO - 10.3329/bjb.v50i4.57091 UR - https://www.banglajol.info/index.php/BJB/article/view/57091 SP - 1209-1214 AB - <p>Effects of salt stress on absorption and distribution of osmotic ions in wheat seedlings were studied with 4 winter wheat varieties under NaCl stress by exploring dynamic changes of Ca<sup>2+</sup>, K<sup>+</sup>, Na<sup>+</sup>, Ca<sup>2+</sup>/Na<sup>+</sup>, K<sup>+</sup>/Na<sup>+</sup> and Na<sup>+</sup> limiting ability. The results showed that the contents of K<sup>+</sup>, Ca<sup>2+</sup> and the K<sup>+</sup>/Na<sup>+</sup> ratio gradually decreased in a manner of both salt concentration dependent and stress time dependent. The extent of reduction of K<sup>+</sup> and Ca<sup>2+</sup> in root was much more severe than that in shoot. The ability of Na<sup>+</sup> limiting in QM6 and DK961 was stronger than that in JM22 and QF1. These results indicate that the maintenance of higher Na+ content in root, Na+ limiting ability, Ca<sup>2+</sup> and K<sup>+</sup> concentration will be the main physiological traits for the salt-tolerance of wheat.</p><p>Bangladesh J.
