Abstract

The amount of mechanical damage evident on potatoes graded by reciprocating square-mesh riddles decreased with increase in tuber temperature prior to grading. In a separate experiment, the extent of rotting by gangrene as a result of artificial infection of the surface of injured tubers was reduced in most cases with increase in tuber temperature at the time of inoculation. The incidence of gangrene in consignments of seed potatoes was reduced by storage at 15 to 17°C for about one week (five to ten days) after grading or after delivery.
