Deformed Tomato Fruit Noses

Have you ever seen a tomato with a “nose” on it? Such weird shaped tomatoes may have what looks like horns as well. What causes tomato noses? Well, it’s a physiological/genetic disorder that occurs in about 1 out of every 1,000 plants. Basically, the problem arises when the fruit is still microscopic. A few cells divide incorrectly and make an extra fruit locule. When you slice into a tomato, they have 4 or 6 obvious segments, which are called locules. As the tomato grows, the genetic mutation that occurred when it was microscopic grows with the fruit until eventually you see a mature tomato with a ‘nose’ or horns. The environment has to do with the genetic mutation. Extended temps of above 90 degrees F. (32 C.) and over 82-85 F. (27-29 C.) at night cause this deformity. It doesn’t necessarily affect the entire plant; in fact, usually only one or two fruits are affected.

I have seen this, before, and it always makes me laugh. And we did just experience a nasty heat wave. Now things have cooled, and the tomatoes have slowed in ripening.
