Genetic diversity of Salix lapponum populations in Central Europe

Salix lapponum is a cold-tolerant relict species in Europe that occurs in several sites, probably reflecting previous migration routes of S. lapponum during the Pleistocene. However, only a few data are available on the genetic structures of populations of S. lapponum. In this study, we use PCR-ISSR...
