Ex situ preservation of germplasm for higher plant species has been accom plished using either seeds or clones, but storage of these under typical condi tions does not provide the extreme longevities that are needed to minimize risk of loss. Cost

Long-term preservation of seed germplasm is a high agricultural priority. It assures that genetic diversity will be available for future generations for continued plant improvement. This experiment reports on the affect that storage temperature had o

Pollen from Clianthus formosus (G. Don) Ford and Vickery was tested for viability after desiccation and exposure to low temperatures. Desiccation for 3 hours before freezing at -180C was sufficient for maintaining pollen germination. Pollen dried for

A high percentage of isolated shoot tips of Solanum etuberosum survived slow cooling at 0.3°C/min to −40°C. Below this temperature survival decreased. High survival could be obtained at −196°C by a two-step procedure of slow cooling to −40°
