Variety traits

Plum sugar content

Prunus domestica L.

A key indicator of fruit quality in Prunus domestica, representing the sugar content as a percentage of mass, determined by refractometric or chemical methods.

In the reference 45 varieties crop European plum, where this is mentioned in the description.

For plum fruits, sugar content values typically range from 15% to 22% or higher. Varieties with values of 15–19% are considered sufficiently rich, while values exceeding 20% indicate a high potential for sugar accumulation, which is important for dessert quality and industrial processing.

Sugar content influences the flavor balance of the fruit, assessed via the sugar-acid ratio, and determines the suitability of the crop for the production of prunes, nectars, and compotes. The level of sugar accumulation depends on lighting and nutritional conditions, while infection of the plants with the Plum pox virus leads to a consistent decrease in this indicator.
