In this article:
Splitting of grape berries can take place before harvesting or during storage.
However, another form of damage occurs as fine concentric surface cracks in the berry skin.
These cracks may have been observed previously, but to our knowledge no reports describing them published.
The purpose of this study was to compare the anatomical structure of cracks and splits, and to establish the extent of damage at the cellular level in each case.
