Cryopreservation of Excised Meristems, Shoot Tips and Somatic Embryos,ore, a relatively retricted experimental literature. Whilst there is no single, definitive protocol which can be shown to be suitable for anything like a comprehensive range of plant species, there are trends and protocols with promise that have been successful for a number of species, and it is these that are reported below.

At its simplest, lowering the environmental temperature of cultures below their active growing temperature is used to significantly extend the interval between subcultures. Care must be taken to avoid tempe

Die Rolle des Teams in der Kundenbetreuung,tained clonally (Withers 1988; Towill 1990a). Cryopreservation of protoplasts, cells, tissues, and somatic embryos is also needed for many tissue culture operations to assure line purity and performance, and to avoid costly, frequent tranfers. Low temperatures reduce maintenance requirements and sho
