The cultivation of oak seedlings inoculated with Tuber aestivum Vittad. in the boreal region of Finland

摘要: Despite recent findings, truffles are rarely found in Finland. In 2006, we began to explore the cultivation potential of Tuber aestivum/uncinatum 2006–2008, roughly 1,200 Quercus robur seedlings and 200 Q. pubescens were planted 20 orchards. We aimed challenge Southern European (France) tree provenances oak a boreal climate. Additional winter coverings made up fabric or plastic twigs prevented seedlings’ mortality even when air temperature was below −30 °C during second winter. The results showed that top soil at 15 cm depth has be above −5 guarantee survival seedlings. more sensitive low temperatures than robur. Morphological PCR analysis root samples collected over 2007–2010 confirmed presence T. aestivum all orchards despite unfavorable time. first sporocarps under October 2012 established 2006 on old agricultural land, showing truffle successful
