"Elephant's Foot," a Basal Stem Disorder in Greenhouse-Grown Bell Peppers
Under certain conditions, vegetable greenhouse crops can develop physiological disorders that predispose plants to diseases that decrease plant growth, fruit yield, and fruit quality. One plant disorder in bell pepper (Capsicum annuum L.) is the “Elephant's Foot,” which is characterized by the presence of epidermal injuries on a swollen stem region developed at the base of the plant stem.
The epidermal injuries increase the plant susceptibility to fungal infections that can lead to plant death. This publication describes the symptoms and possible causes of this basal stem physiological disorder in greenhouse-grown bell pepper, and presents pepper production methods to avoid the disorder.
