Watercore

Watercore is present already at harvest. The affected tissue is water-soaked and glassy. It is usually not visible from the outside. When you find watercore before the start of storage, you need to adapt your storage conditions. When the area of this water-soaked tissue is limited, apples can still be stored well and the glassy areas will disappear without damage. However, when it is more severe and stored under too low O2 and/or high CO2, the tissue can turn brown.
