Effect of Salt (NaCl) Stress on Germination in Clary Sage (Salvia sclarea) Subjected to Gibberellic Acid Pre-treatment

Abstract

The research aimed to ascertain how adding GA3 to Salvia sclarea L. (clary sage) seeds before germination affected the process of seed germination in saline environments. Four different concentrations of NaCl (0, 50, 100, and 150 mM) and four different concentrations of GA3 (0, 50, 100, and 150 ppm) were used in the study. This research was conducted with four replications according to the Randomized Blocks Split Plots Trial Design. The following criteria were examined in the study: root length (cm), stem length (cm), germination strength and germination rate (%). This investigation revealed that higher salt concentrations had a detrimental impact on germination. It was determined that GA3 application applied before germination significantly eliminated the inhibitory effect of salt stress on the germination of Clary Sage seeds. In addition, the highest values in the criteria discussed were found in the averages of 0 mM NaCl and GA150 applications.
