In viticulture, the grape cluster (also bunch of grapes) is a fertilized inflorescence of the grapevine, the only part of this plant used for food.[1]
Structure
editThe placement of a cluster on the vine is similar to a tendril.[2]
The grape cluster is shaped as a panicle, with the main branch ("axis") called rachis. Additional branches ("shoulders") are connected to the rachis irregularly and split into pedicels (short stems attaching individual berries). In a large cluster, the shoulders might bear secondary and sometimes tertiary branches before ending up with pedicels. The beginning of the rachis before the first split is called a peduncle.[2]
