Potato Physiological Disorders—Internal Heat Necrosis

The potato (Solanum tuberosum) is a herbaceous annual that grows up to 100 cm tall and produces a tuber – also called potato – so rich in starch that it ranks as the world’s fourth most important food crop, after maize, wheat and rice. As the potato plant grows, its compound leaves manufacture starch that is transferred to the ends of its underground stems (or stolons). The stems thicken to form a few or as many as 20 tubers close to the soil surface.

"Florida's agricultural industry generates more than $103 billion in annual economic impact and employs more than 500,000 people. Florida's farmers produce nearly 300 commodities, and winter vegetables and citrus consistently lead the national rankings. To meet the needs of this diverse industry, research and extension programs in the areas of fruit and vegetable production, postharvest technology and weed science are delivered on a county, regional and statewide basis using a variety of methods including field days, intensive hands-on training, and distance learning. Excellence in programming facilitates the exchange of information and technology and contributes to the professional development of extension faculty and the agricultural clientele they serve."
