Zippering
Return to Physiological Disorders
Zippering is characterized by the presence of brown tissue (resembling a zipper) running down the sides of tomato fruit, often from the stem to blossom end. Zippering is the result of a flower anther remaining attached to newly forming fruit. It may be associated with incomplete shedding of lower petals when fruit is forming.
