There are a number of non-pathological disorders seen in marketed fruit (Paull et al. 1997; Sivakumar and Wall 2013). The disorders include the following:Green, slightly sunken areas on ripe yellow fruit are due to abrasion injury that occurs when fruit are still green (Quintana and Paull 1993). Unsightly skin freckles (small brown slightly raised areas) that are more common on the side of the fruit exposed to the sun and are seasonal, occurring when rainfall and low temperatures occur 2 mo before harvest (Reyes and Paull 1994). This disorder is non-pathogenic and does not influence ripening or flavor. Sun scald, a dark olive-brown discoloration, occurs on fruit developing on trees with very sparse foliage; on
trees that are leaning over, with fruit directly exposed to the sun; and where harvested fruit are left exposed to
the sun. Blossom end defect can be severe at some times of the year (Zee et al. 1989). The disorder leaves an open channel at the blossom end to the fruit seed cavity. Fruit with this disorder are prone to bacterial diseases in the
fruit seed cavity before harvest.
