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… CONTINUE READING
