To determine the biochemical and physiological responses of potato tubers to controlled atmosphere storage. - HP0205

Objective
To extend knowledge of the physiology and biochemistry of the effects of controlled atmospheres on potatoes in storage, using a range of different cultivars and current commercial production systems. This will allow the development of a robust model which can be used to predict the 'storability' of potatoes in any given year based on husbandry and crop status (pre-harvest) similar to the systems being developed for apples. In addition, we intend to explore further the use of controlled atmospheres to control and manipulate the apical dominace relationships in stored tubers. It has been impossible to store ware tubers consistently for any great period of time without the use of sprout suppressants or by reducing the temperature. During the current project it has been shown that it is possible to control the sprouting of potatoes in storage for long periods by manipulating the concentrations of oxygen and carbon dioxide in the storage atmoshere. In addition, but in different conditions, it has been possible to break the apical dominance relationships in stored tubers and increase the number of sprouts per tuber.
