Allium ursinum L. in Germany – surprisingly low genetic variability (Herden, T., Neuffer, B. and Friesen, N. (2012), Allium ursinum L. in Germany – surprisingly low genetic variability. Feddes Repert., 123: 81–95. doi: 10.1002/fedr.201200019 ) is an interesting article about biogeography of Allium ursinum ,stating:
“Sequences of the nuclear internal transcribed spacer ITS, and the external transcribed spacer ETS, as well as the plastidic trn L-rpl 32 and the trn L-trn F spacer regions were compared. No variation was detected within the species. Even sequences of populations from Belfast, Ireland did not differ from populations of Germany”
What does it mean?Basically that Allium ursinum plants from the following old illustrations are probably genetically almost identical as the plants being sold on Ljubljana grocery market today!Have a look!
