Sprouting of- and fungal attack on tuber, bulb and foot products is a common problem to most countries. Sprouting can be delayed by storage at low temperature, and partly prevented by a proper use of chemical sprout inhibitors. Cooling is, however, energy consuming, expensive and not practicabie everywhere. Chemicals are cheaper, but their application is not always reliable, especially at temperatures higher than 15'C. Moreover in some countries the application of chemical inhibitors is prohibited. From research it has been proven that sprout inhibition can also be achieved by an irradiation treatment. However, this treatment can induce rot during storage, especially in (semi)tropical countries. The appearance of rot in potatoes depends of different factors like irradiation dose, postharvest irradiation time, wound healing, dormancy period, storage temperature etc. To solve this rot problem these factors have to be studied. In relation to this probem the following research was set up with the aim: study the effect of a postharvest and postponed irradiation treatment with different doses on sprouting, rot incidence, wound healing, chemical and sensory properties of potatoes. In the framework of this project two experiments were started in September 1985 with the potato cultivar "Bintje". One experiment was focussed on the sprout inhibition and the other on the control of rot. These experiments have been finished at July 1986.
