Tomato Biological Clock

Someone I met in my community garden today was ranting about how her tomatoes have a biological clock. Her logic is this. First, the tomato plants were mortally wounded by an early but quite potent snow storm. Next, the plants survived, but wilted beyond recognition. Third, the began to madly make tomatoes. Her logic: the plants are dying so they start to make seeds and procreate with the intention of passing along life to the next generation because they would soon be done with this world. You can tease me as much as you want about tomatoes not having a brain, but I at least half agree with that crazy woman!!
