Potato Skin: The Best Defense Against Storage Loss

Potato Skin: The Best Defense Against Storage Loss

Protecting the skin from injury is one of the most effective ways to keep potatoes healthy in storage. A potato that is undamaged defends itself against disease, retains water, and maintains quality over time. In this presentation, we will review the properties of the skin that allow it to be an effective barrier against pathogen entry and water loss. We will also discuss skin formation, skin set, and wound healing. before considering management practices that contribute to maintenance of the skin from field to storage.
