Özet
Tannery effluents contain not only valuable nutrients, but also salts, heavy metals, some pathogens, dying agents, etc. It is one of the ten most harmful concerns to the environment because of the lack of proper waste disposal applications. This present study was conducted to determine the effects of tannery wastewater on some germination properties of wheat, maize, rice, chickpea, bean, sunflower and soybean seeds, which are of great importance for crop production of Turkey. The experiment was laid out in a completely randomized block design with three replications. For these purposes, four concentrations of the effluent (1:0, 1:10, 1:40 and 1:80) including tap water as control were analyzed for some physical and chemical properties, and used in irrigations for germination of the seeds in Petri dishes. The numbers of germinated seeds at 48(th), 96(th), 144(th), 192(nd), 240(th) and 288(th) hours were counted. Root and hypocotyl lengths were measured at 96(th) hour for wheat, at 192(nd) hour for sunflower and soybean, at 240(th) hour for rice, chickpea and bean, and at 288(th) hour for maize. Chemical analysis of the effluent revealed that it is rich in some plant nutrients; however, different concentrations of the effluent had negative effects on seed germination and plant growth. As a result, undiluted tannery effluent (1:0) significantly decreased and inhibited seed germination compared to the other concentrations. All the characteristics investigated in the study were affected by effluent applications (P < 0.05).
