Water core in apples: what is it, what causes it and how can it be controlled? Water core (Fig. 1) is one of the many physiological disorders affecting apples. Physiological disorders are abnormalities in the various apple tissues that result in loss of quality, loss of marketability and increased loss of fruit that is discarded and not consumed. These disorders are caused neither by fungi, insects or viruses, nor by mechanical damage. The incidence of water core can vary from year to year. Not all apple varieties are affected equally, some of the most susceptible being Cox's Orange Pippin, Delicious, Fuji, Braeburn, Jonathan, Stayman, Starkrimson, although it can also be detected in Golden Delicious, Granny Smith and McInstosh, among others.

Sunburn on apples is irreversible damage that occurs to the fruit. Read more about how it happens and its prevention.

Russet on apples is a disorder of the skin that results in discoloration and changes to the ex-pected smooth texture of the skin of apples. Russet appears as a spectrum from mild brown weblike pat-terns to severe rough changes on the surface of ap-ples and many variations in between (Fig. 1). Rus-seting is only skin deep and thus will not affect the flesh of the fruit. It can occur due to naturally-occurring weather conditions, particularly humid and wet weather.
