Summer eye

Also summer bud; see under eye.

Term (in botany also bud or gemma) for the juvenile state of a new shoot or shoot. On the vine, the eye is located in the leaf axils on 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 that 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 (fastening organs) and inflorescences (legs). 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 budding in spring. At the site of the nodes is the diaphragm (wooden bridge).

Main eye and secondary eye

In addition to the main eye (plant for the main shoot), each winter bud also contains two lateral eyes (lateralis = lateral) at the base of the bud base. These are also already pre-differentiated, but have a simpler structure and serve as replacement buds in an emergency. As a rule, they only sprout when the main eye or the young shoot emerging from it has been destroyed by external circumstances such as early frost, game browsing (by deer or hares) or insect damage, or remains inhibited in growth in spring,...

The glossary is a monumental achievement and one of the most important contributions to wine knowledge. Of all the encyclopaedias I use on the subject of wine, it is by far the most important. That was the case ten years ago and it hasn't changed since.
