So there might be a typo in the wiki. I hope the person who wrote the sarniensis part of http://pacificbulbsociety.org/pbswiki/index.php/… will let me know more about that Netherlands research. I googled to see if I could find the Netherlands research but couldn't. Can we assume an extra numeral has been added? Maybe they meant 7C. Or maybe the 1 was supposed to be a minus sign - 7C Does that temperature make sense? I read about all the other species, and some of them require a jolt of cold in the winter or they won't flower.
