Quiet a number of maladies can plague the tomato fruit. If you have noticed abnormal cavities pitted with scar tissue and swelling, your tomato may be afflicted with cat-facing fruit deformity. Cat-facing refers to a type of physiological damage affecting tomatoes and represented by scarring and cavities near the blossom end.
So called since the abnormal cracking and dimpling on tomatoes looks somewhat akin to a small cat’s face. Basically, it is the abnormal development of plant tissue affecting the ovary or female sex organ which results in the flower, followed by the fruit development to become malformed. In concentric cracking, the fruit develop circular, concentric cracks around the stem end of the fruit.
In radial cracking, the fruit cracks radiate form the stem end. Cat-face is expressed as malformation and cracking of fruit at the blossom end, often exposing the locules.
