Eye

Term (in botany also bud or gemma) for the juvenile state of a new shoot or sprout. In the vine, the eye is located in the leaf axils at the nodes of one-year-old shoots, which is why it is also called axillary bud or axillary bud. The so-called winter eye consists of woody bracts, which are stacked in several layers and enclose the primary, already pre-differentiated plants of the new shoot. Already visible in miniature are the shoot segments of the shoot axis with the laterally angled appendages for leaves (foliage), tendrils (attachment organs), and inflorescences (scapes). The cavities in the bud are filled with fine woolly hairs, so that the shoot is protected from physical injury, frost and moisture during winter dormancy until budbreak in spring. At the site of the nodes is the diaphragm (wooden bridge).
