Potassium Fertilization Enhances Anthocyanin Accumulation And Red Coloration Of Apples Fruits
How to Improve fruits Colour?
Potassium
Potassium (K) fertilization enhances anthocyanin accumulation and red coloration of apples by compensation of some of the negative effects of higher nitrogen rates on apple coloration.
Light
The biosynthesis of anthocyanins is strongly light dependent. Some preharvest practices such as pruning, reflective mulches and use of shoot growth retardants improve fruit skin colour.
Temperature
Colouring of apple fruit is increased by low temperatures such as those encountered on cold nights, especially on poorly exposed areas. If cool night temperatures are followed by excessive (> 30 °C) daytime temperatures, the positive effects on anthocyanin synthesis will be negated. The critical colouring period, in regards to temperatures, is two to three weeks before harvest. Optimum temperatures for red colour formation vary among cultivars, but are generally between 20 and 25 °C.
Reconmmendation dosage
During the second expansion period of fruits to the color change
period, 1-1.5KG per hectare.
Application crops
All fruits trees especially for grape, pineapple, banana, pear and
so on.
Packing: 200L or 1000L per drum or customized.
