Interpretive Summary: Cryogenic storage of apical meristems is being used by the US Department of Agriculture, Agricultural Research Service, National Plant Germplasm System as base (long-term backup) storage for several temperate fruit (pear, currant, gooseberry, blackberry, raspberry) and specialty crops (hops, mint, grass). Cryopreservation protocols are defined for many types of plants and many plant forms (seeds, pollen, dormant buds, and apical meristems). Long-term storage for vegetatively propagated plants has always been difficult. Cryogenic storage provides security for the select cultivars important to horticulture and agriculture. Several protocols are now available for use with diverse crops. At the National Clonal Germplasm Repository controlled dehydration (Encapsulation-dehydration)is a successful technique for many crop types. This web presentation outlines the steps for the basic technique and a modification. With proper manipulation most clonally propagated plants can be stored for future generations.

Technical Abstract: Cryogenic storage of apical meristems is being used by the US Department of Agriculture, Agricultural Research Service, National Plant Germplasm System as base (long-term backup) storage for several temperate fruit (pear, currant, gooseberry, blackberry, raspberry) and specialty crops (hops, mint, grass). Cryopreservation protocols are defined for many types of plants and many plant forms (seeds, pollen, dormant buds, and apical meristems). Long-term storage for vegetatively propagated plants has always been difficult. Cryogenic storage provides security for the select cultivars important to horticulture and agriculture. Several protocols are now available for use with diverse crops. At the National Clonal Germplasm Repository controlled dehydration (Encapsulation-dehydration)is a successful technique for many crop types. Bermuda grass and Zoysia grass,currant, gooseberry, and hops are all successfully preserved using this technique. This web presentation outlines the steps for the basic technique and a modification. With proper manipulation most clonally propagated plants can be stored for future generations.
