Abstract
Osmotic stress is a major concern in agricultural production because it can negatively affect plant growth, development, and productivity. In this study, the effects of Gibberellic Acid (GA3) and Boric Acid (Br) on germination and seedling development as pre-application of polyethylene glycol (PEG) to rapeseed (Brassica napus L.) seeds were examined. The research was conducted at the Field Crops Laboratory of Sakarya University of Applied Sciences, Faculty of Agriculture. In the experiment, the seeds were pre-treated with five different concentrations of GA3 and Br (control, 0.50, 1.00, 1.50, 2.00 mg l-1) before planting, and then four different concentrations of PEG (6000) (control, -0.4, -0.8, 1.2). Mpa) were subjected to drought stress. The experiment was conducted with three replicates according to a Randomized Plot Factorial Trial Design. In this study, the germination rate, germination power, seedling length, root length, water content, and seedling fresh and dry weight characteristics were examined. In this experiment, as drought stress increased, decreases in germination rate and germination power and negative effects on other seedling characteristics were detected. However, when we examined the germination and seedling characteristics according to the research results, it was seen that the application of 1.5 to 2.00 mg l-1 Br in -0.4 Mpa PEG stress generally gave positive results against drought stress. As a result, it was concluded that Boric Acid application to rapeseeds under PEG stress conditions may be beneficial during seedling development as an alternative to plant regulatory groups.
