Most Tennessee crop producers are familiar with the term "crazy cotton," which refers to the loss of apical dominance in a cotton plant.
Apical dominance is when a plant has one primary central stem with branches extending off of it. However, some cotton plants are losing apical dominance and growing their central stem in a "V" shape, often resulting in fewer bolls per plant.
Graduate student Gabby Marotta has made this phenomenon the focus of her PhD research, and she spent this past summer at WTREC investigating potential causes.
