Blueberry bloom

Vaccinium corymbosum L.

The waxy bloom on highbush blueberry fruit is an important protective layer that limits transpiration and prevents the development of rot. It gives the berries their characteristic blue hue and serves as an indicator of market quality during breeding and storage.

In the reference 73 varieties crop Highbush blueberry, where this is mentioned in the description.

The physical presence of the waxy bloom on the berry surface provides biological protection, reducing the risk of dehydration and infection by phytopathogens during storage. Mechanical damage to the layer exposes the skin, which manifests as a glossy appearance on the fruit and significantly reduces its commercial appeal.

In variety trials, bloom intensity is evaluated by expert methods using a scoring scale or instrumentally through surface gloss analysis. The average wax content in highbush blueberry varieties is about 120 mcg/cm², and varieties with a more stable and intense bloom possess better suitability for transport.
