Özet

This research was conducted to determine the effects of priming treatments (GA3, KNO3 and Hydropriming) on germination and seedling growth in perennial ryegrass contaminated with different doses (0, 75, 150, and 300 mg l-1) of cadmium and nickel. The study was conducted under laboratory conditions. Perennial ryegrass cv. Integra was used as the plant material. The results showed that both germination and seedling growth properties were adversely affected by heavy metals. The adverse effects of nickel were more pronounced than those of cadmium. The GA3 seed priming pretreatment had positive effects on both germination properties and seedling growth. As a result, GA3 can be used as a seed priming agent if the perennial ryegrass is to be grown in areas contaminated with nickel and cadmium.
