Abstract
Results of potato tuber impact damage tests depend primarily upon velocity and energy of impact. Blackspot and shatter indexes correlated poorly with tuber mass, storage time and each other. However, the shatter index became much less variable with increased storage time. Impact velocity and energy correlated quite well with rebound angle (r = 0.92 for each) and shatter index (r = 0.99 and 0.98 respectively). However, the size of the surface of the impact head correlated poorly with rebound angle and shatter index. The rebound angle: 1) correlated with tuber mass (r = 0.83), 2) was random over storage time, 3) correlated poorly with shatter index (r = 0.40), and 4) had no correlation with blackspot index.

El resultado de las pruebas de golpe de los tubérculos de papa depende principalmente de la velocidad y fuerza del impacto. Los índices de mancha negra y de fraccionamiento correlacionaron pobremente con la masa del tubérculo, el tiempo de almacenamiento y entre ellos mismos. Sin embargo, el indice de fraccionamiento result6 mucho menos variable con el mayor tiempo de almacenamiento. La velocidad y fuerza del impacto correlacionaron bastante bien con el ángulo de rebote (r = 0,92 para cada una) y el índice de fraccionamiento (r = 0,99 y 0,98 respectivamente). Sin embargo, el tamaño de la superficie impactada correlaciono pobremente con el ángulo de rebote y el índice de fraccionamiento. El ángulo de rebote: 1) correlacionó con la masa del tuberculo (r = 0,83), 2) no estuvo correlacionado con el periodo de almacenamiento, 3) correlacionó pobremente con el índice de fraccionamiento (r = 0,40) y 4) no tuvo correlatión con el indice de mancha negra.
