Lenticel breakdown occurs because of microcracks and abrasions on the epidermis layer of apples preharvest. These microcracks and abrasion can occur due to irregular water supply, as well as high humidity (> 95%), and low wind. Influxes of water in addition to low rates of evapotranspiration causes fluctuations in the amount of water within the apples and equate to this irregular water retention. Lenticel breakdown occurs mainly on the apple skin around the lenticels of the fruit, on the less exposed side of the fruit. They are characterized by precise circular darkened spots concentrated in multiple areas on the skin of the apple. Early symptoms are similar to small dimples, visible in angled light. During storage, as flesh firmness decreases, spots grow in depth and diameter and may combine. Flesh is not generally affected. From here.
