Effects of Different Salt Concentrations on Germination and Seedling Development in Forage Turnip
Abstract
Objective: This research was carried out to determine the effects of different salt concentrations on germination and seedling development in leaf type forage turnip (Brassica rapa L.).
Materials and Methods: In the study, seeds of the Lenox variety were germinated in 0, 50, 100, 150 and 200 mM NaCl solutions at 24±1 0C in darkness. The study was conducted in a randomized plot design with 4 replications. Germination percentage (%), potential germination (%), mean germination time (days), germination uniformity, germination rate, radicle and plumule lengths (cm), and seedling fresh weight (g) were determined. The data obtained from the study were analyzed by one-way ANOVA, Welch ANOVA, and Kruskall-Wallis statistical analysis methods. Tukey, Games-Hovel, and Bonferroni tests were used as multiple comparison tests.
Results: In this study, where different salt doses were applied to leaf-type forage turnip seeds, the differences amongs to salt concentrations were found to be insignificant in terms of mean germination time and germination uniformity. However, the effect of salt concentrations on all other parameters examined in the study was found to be statistically significant. When 50 mM NaCl was present in the germination medium, germination percentage, germination rate, and potential germination increased compared to the control, but decreased with increasing doses. The first negative effect of salt on seedling development occurred at the 50 mM.
Conclusion: Although germination increased in the 50 mM NaCl solution compared to the control, seedling development was negatively affected, leading to the conclusion that the plant is sensitive to 50 mM salt concentrations in the early seedling stage.
