Summary

DURING STORAGE OF POTATOES, LOSSES IN QUALITY AND QUANTITY OCCUR, CAUSED BY SPROUTING, RESPIRATION, EVAPORATION AND MICRO-ORGANISMS. AFTER DORMANCY, TUBERS START SPROUTING WHEN THE TEMPERATURE REMAINS OVER 277 K (4 DEG C). THERE IS INCREASED SPROUTING UP TO ABOUT 293 K (20 DEG C) ; AT 298 K (25 DEG C) SPROUTING IS LESS VIGOROUS. LOSSES BY RESPIRATION ARE INEVITABLE, BUT CAN BE MINIMIZED BY STORAGE AT 278 K (5 DEG C). EVAPORATION CAUSES MUCH HIGHER MASS LOSSES AND DEPENDS ON THE TEMPERATURE DIFFERENCE, THE RELATIVE HUMIDITY OF THE AIR AND THE CONDITION OF THE SKIN. IN THE FIRST MONTH THE TOTAL MASS LOSSES DUE TO RESPIRATION AND EVAPORATION AMOUNT TO 1-3% FOR WARE AND 2-5% FOR SEED POTATOES.
