Effects of Pre-Germination in Acetyl Salicylic Acid Solutions on Germination and Emergence of Carrot Seeds Under Salt Stress

Abstract

In this study, the effects of pre-germination at different doses of acetyl salicylic acid (ASA) solution on the germination and emergence performance of “Nantes” carrot cultivar (Daucus corata L.) seeds under salt stress were investigated in the laboratory conditions. Seeds were pre-germinated in a climate cabinet for 24 hours in 0, 50, 100 and 150 mg L-1 ASA solutions in hydropiriming at 15oC. After this process, they were divided into two groups as pre-germination and control groups. Both groups were exposed to the stress of 0, 50, 100 and 150 mM NaCl, and the response of ASA application to salt salt ster was investigated. As a result of the research, it was determined that high salt concentration (150 mM NaCl) decreased the germination of carrot seeds, and high dose ASA pre-applications affected the germination and emergence parameters of the seeds. According to the results, the highest germination rate was determined with 93% in the 0 and 50 mM NaCl interaction in the 150 mg/L ASA application in dose x salt interaction. It has been predicted that ASA applications increase the germination rate of seeds in low and high salinity growing environments and can be used successfully.
