| Abstract: | The latest achievements of the research in in vitro conservation of fruit germplasm are summarized in this paper. Fruit seeds preservation and some common methods of fruit tree cell, tissue and organ preservation are briefly mentioned. The theory,affecting factors,key technology and the main merits of cryopreservation,an ideal method for long-term conservation for fruit germplasm are introduced in details. Some factors which affect the results of cryopreservatoin, including material characters, pretreatment, cryprotectants, freezing and thawing methods are discussed as well. Some points for improving fruit germplasm conservation in the future are recommended. |
