The shoot tips of a periclinally chimeric cultivar of chrysanthemum (cv. Apricot Marble) were excised, loaded with cryoprotectants and cryopreserved. Amongst plants derived from conventional shoot tip culture, 99% had normal flower colour. In contrast, 70% of plants derived from cryopreserved shoot tips had a pink flower colour instead of the original apricot. The pink petals contained anthocyanins in the epidermis but lacked carotenoids in the epidermis and mesophyll.
