Abstract

Relationships between the ultrastructure of plastids and the phases of the vegetative cycle of latent buds of the vine (Vitis vinifera L. var. Ugni blanc)

Salient features in the development of plastids and starch of the central bud into dormant buds of the vine occur during the stages of dormancy called ,,entrée en dormance" and ,,levée de dormance". Prolamellar bodies differentiate into plastids during the first stage and starch is hydrolysed during the later one. Starch changes in the plastids of central buds occur in agreement with the changes of glucid amounts in shoots.
