Abstract :This research was conducted at Department of Field Crops in Faculty of Agriculture in Yüzüncü Yıl University in 2014 , in the growth chamber under controlled conditions in terms of temperature and light, for 5 bread wheat varities (Doğu-88, Altay-2000, Bezostaja1, Alparslan and Tir mixed population line), for two different irrigation levels (using 40% of the field capacity for drought and 60% for control), through the application of two different salicylic acid dosage (0.1 mM kg-1 SA and 1.0 mM kg-1 SA), with four repetitions in 80 pots with 4 kg soil capacity, with respect to randomized experimental design principles. In terms of the investigated characteristics, salicylic acid applications were found to be effective for the Bezostaja1, Doğu-88, Altay-2000 varieties and Tir wheat population line by enhancing their tolerance to drought and exhibited differences with respect to the salicylic acid doses (0.1 mM kg-1 and1.0 mM kg-1). The characteristics, which were adversely affected when compared to the control application under drought conditions, were commonly positively affected by the salicylic acid applications.
