Popis: Hollow heart is a defect which can cause serious problems in marketing potatoes. X-ray inspection is recognized as one of the most reliable non-destructive techniques for detecting hollow heart in white potatoes. Tests were conducted on potatoes having various degrees of severity of hollow heart and also on normal tubers. X-ray pictures were effective in exposing the hollow heart condition. The radiographic contrast between normal and defective tubers was enhanced by examining the tubers submerged under water. The x-ray image of sound potatoes was masked entirely while the hollow heart areas appeared as a bright spot under water. Results suggest that automatic sorting of potatoes for hollow heart may be simplified considerably if the tubers are x-rayed in a stream of water rather than in air.
