Minimizing Top Fruit Internal Breakdown
Crop Nutrition and Internal Breakdown
Phosphorus
Phosphorus can help reduce internal breakdown occurrence. By ensuring supplies to the fruit are not limiting, internal cell wall collapse is avoided and low temperature breakdown and internal browning minimized.
Trials show that phosphate improves long-term storage characteristics in apples and reduces storage disorders incidence such as internal browning and core flush.
Calcium
Low calcium nutrition increases the incidence of internal breakdown. Soil supply is important, but it should be backed by fruit applied sprays. The greater the number of sprays the better, it gets more calcium into the fruit, improving its health and quality.
Boron
Excessive boron increases the incidence of top fruit internal breakdown.
