Water Core
- This physiological disorder is promoted by high leaf to fruit ratio, high levels of nitrogen and boron in the fruits, low levels of fruit calcium, excessive thinning, and exposure of fruits to high temperatures.
- Large size fruits are mostly susceptible to this type of disorder.
Symptoms
- Disorder at pre-harvest stage results in the development of water-soaked regions in the flesh.
- These regions are hard, glassy in appearance and only visible externally when infection is very severe.
- Severely affected fruits may smell and have a fermented taste.
- Water-soaked areas are found near the core or on the entire apple. If symptoms are mild to moderate, they may disappear completely in storage.
