Seed of Salix bebbiana, S. discolor, and S. eriocephala was stored at two moisture contents (5.1-7.3% and 8.5-9.8%) and four temperatures (4, -20, -80, and -196 C) for 24 months. Seed stored at 4 C did not maintain viability. Storage at sub-freezing temperatures maintained seed viability for 24 months with little variation among treatments. Results demonstrate that cryopreservation of Salix seed is possible but does not offer any significant advantage over traditional storage at -20 C.
