Abstract:

The structure of plantlets of Dianthus caryophyllus cv. Cerise Royalette was studied at various developmental stages. In vitrified plantlets there were the following main differences from normal structure: (a) reduction in the period in which cells remain meristematic in developing parts of the shoot, up to full maturation of the shoot apex itself; (b) hypertrophy of the cells, with a loss of a clear axis of elongation; (c) defective cell walls in which disintegration occurs at certain regions to form cavities. © 1987 Annals of Botany Company.
