The effects of GA3 treatments and nutrient media on in vitro seed germination of Allium tuncelianum (Kollman), Özhatay, Matthew, Şiraneci

Abstract

In this study, the effects of GA3 and nutrient media on in vitro seed germination of Allium tuncelianum (Kollman), N. Özhatay, D. Matthew, Şiraneci, which is one of the endemic plants in Turkey, were investigated. In order to promote seed germination, GA3 was applied to seeds under sterile conditions for 48 hours at different concentrations (2 mgL-1, 3 mgL-1 and 4 mgL-1). Then the seeds were cultured in BDS and MS medium in a sterile cabinet. The results showed that the germination rate decreased with the increase of the applied concentrations of GA3. The highest germination rate (17.73%) was obtained from seeds treated with 2 mgL-1 GA3. It was determined that the effects of nutrient media on the germination of Allium tuncelianum seeds were important, and the highest germination values were obtained from the BDS medium.
