| Abstract: | We examined changes in the pattern of leaf variegation in a periclinal chloroplast chimera of Hedera helix L. cv. Goldheart to determine whether stable apical initials exist in the shoot apex. Additional data were obtained by histological analyses. All of the data indicate that four apical initials are present in the third layer of the apex, supporting the model of a structured apical meristem. |
