The sexual determination system in Salix L. (Salicaceae)

Current knowledge of the sex determination system that has been analyzed in different species of the genus Salix L.is reviewed. In this genus, sexual chromosomes have been recognized and it was proposed that a gene for sexual determination must be present. In the genus Salix there are two systems of...
