CRYOPRESERVATION OF DORMANT BUDS FROM TEMPERATE FRUIT CROPS TO OPTIMISE WORKING COLLECTION RESOURCES
The water content of dormant Malus buds is comparable throughout the stages of the cryopreservation protocol, regardless of whether they come from cultivars that survive cryopreservation well or poorly. However, thermal analysis of dehydrated and frozen/thawed buds suggests that the distribution of water within them is different, with those from cultivars that recover poorly from cryopreservation retaining a greater bulk volume of freezable water (estimated by simple thermal analysis [STA]) than tolerant cultivars. Implications for the design of successful cryopreservation protocols for dormant buds are discussed.
