Development and refinement of cryopreservation protocols for the long-term conservation of aroids, namely Alocasia, Colocasia, Cyrtosperma and Xanthosoma species.
The current project aims at developing/refining cryopreservation techniques for taro and other edible aroids. Once these techniques are available and fully operational, their application in the SPC CePaCT, and other relevant genebanks will ensure safe and efficient long-term storage, thereby contributing to the improved conservation of these crops of global importance for food security and nutritional security.
Recently, preliminary experiments have been carried out on Cyrtosperma merkusii (swamp taro). To date two treatments have been tested on the exposure time to Plant Vitrification Solution 2 (PVS2); 10 and 12 minutes respectively. Results indicate that the best exposure time was 12 minutes where an emergence of shoots was apparent, whereas for the 10min exposure time the shoot tips were observed to be bleached. As these are preliminary trials, further experiments have to be established before any conclusions can be made.
