Abstract Background We are studying the regulation of flowering in perennial plants by using diploid wild strawberry Fragaria vesca L. as a model. Wild strawberry is a facultative short-day plant with an obligatory short-day requirement at temperatures above 15 C. At lower temperatures however flowering induction occurs irrespective of photoperiod. In addition to short-day genotypes everbearing forms of wild strawberry are known. In
