Cryopreservation of in vitro grown shoot tips of Diospyros kaki thunb. using different methods

Cryo Letters. 2012 Jan-Feb;33(1):69-74.

Abstract

The objective of this study was to compare the potential of different cryopreservation strategies for in vitro shoot tips of Diospyros kaki Thunb. The treatments consisted of three different cryopreservation methods: vitrification, droplet-vitrification and modified droplet-vitrification. The following variables were assessed: cold acclimation, sucrose concentration in the preculture medium and PVS2 treatment time. A higher average survival level was obtained using the modified droplet-vitrification method compared to the other two methods.
