Abstract
Fruit discolouration of light coloured sweet cherries grown in Norway was investigated during the seasons 1984 and 1985. Fruits were dropped onto a smooth, hard surface and then stored before discolouration was measured by sensory evaluation. High correlation was found between drop heights and fruit discolouration. The fruits were significantly more injured at 0°C than at any other temperature tested. Six cultivars were tested. ‘Merton Glory' and ‘Sue’ were least affected by discolouration. Fruits that were “slightly unripe” became significantly more injured than “medium ripe” and “ripe” fruits. The discolouration of fruits at the bottom layer of the picking bucket increased with increasing total amount of fruits in the bucket.
