Abstract: Drought stress and salt stress often causes serious problems in wheat production areas. A study was conducted in the greenhouse of the Institute of Molecular Biology and Biotechnology, The University of Lahore effects on the seedling growth and development under NaCl treatments in wheat variety UJALA-2017, FAISLABAD-2008 and GALAXY-2013. The data was collected for various seedling traits and statistically analyzed, which revealed the significance of results for treatments, salt applications, genotypes and the interactions between salt treatments and genotypes. It was concluded from our study that the application of salicylic acid (SA) under salt (NaCl) stress conditions helps wheat seedlings to withstand and compete with stressful conditions. The study revealed that the seed priming with salicylic acid helps to improve root length, shoot length. The use of SA priming shows medium effects for the seedling growth of wheat under salt stress environmental conditions. The wheat variety Galaxy-2013 has shown good performance for most of the studied traits of seedlings under salt stress conditions. It was suggested from our study that the variety Galaxy-2013 may be used under salt stress conditions or salt affected soils to improve grain yield of wheat.
