Turkish hazel: testing six seed sources at five locations in Sweden and Denmark

In the spring of 2024, SLU planted a seed source (‘provenance’) experiment with Turkish hazel at Alnarp, Tönnersjöheden and Remningstorp in Sweden and Moselund and Sæby in Denmark. The experiment was laid out in randomized blocks and included six different seed sources: three from Turkey, one from Hungary, one from Germany and one from the Netherlands. All six seed sources were replicated in five blocks at each site and nine times within each block. All trees were measured for total height at planting, forks were singled and strongly ascending branches were removed. The experiment included wild apple and pear for separating blocks of Turkish hazel. As an appendix, this report also includes the establishment report for two pilot provenance experiments with Turkish hazel and wild apple planted in a mixed stand at Sæby in Denmark.
