Dry Matter Partitioning and Ion Accumulation in Spring Wheat (Triticum aestivum L.) as Affected by Soil Salinity and Growth Regulator (IAA) Spray
Shazia Naseer

Abstract: In a pot experiment with spring wheat cv. Kohistan-97 and Parwaz-94, the effect of foliar application of IAA and different salinity levels 8, 12 and 16 dS m -1 on dry matter partitioning and ion accumulation was studied. With the increase in salt concentration, there was decrease in roots, culms and leaves dry weights. The reduction in dry weights was more in Kohistan-97 than Parwaz-94. The Na+ and Cl+ contents in roots, culms and leaves increased with increasing salinity while K+ content decreased. Spraying with IAA proved effective in ameliorating the adverse effect of salinity on dry matter and ion accumulation, whether applied at the time of salinization or 15-days after salt treatment.
