The factorial experiment based on completely randomized design performed in growth chamber conditions with four replicates. In experiment, parameters such as leaf area, chlorophyll content, ion leakage in leaf tissues, MDA levels, relative water content in leaf tissues and membrane endurance index were investigated. In study, it was determined that salt stress decreased leaf area, chlorophyll content, membrane endurance index, relative water content in leaf tissues; MDA levels with ion leakage in leaf tissues were increased. All of the investigated parameters increased significantly except for MDA level and ion leakage in leaf tissues due to seaweed applications. Keywords : Seaweed; Salt stress; Echinaceae purpurea L.
