Effect of Pre-soaking Seed Treatments with Plant Hormones on Wheat under Conditions, of Soil Salinity

The germination of wheat decreased with the increase in the level of salinity, but improved by seed soaking treatments with IAA, NAA and GA under different levels of salinity. The grain and straw yield of wheat was reduced significantly due to medium and high salinity levels. Similar trend was observed in case of uptake of nutrients (N, P, K, Ca, Mg and B). The seed soaking treatments with IAA, NAA and GA increased the yield as well as the uptake of nutrients significantly.
