Résumé

In experiments conducted at the Research Institute of Vegetable Crops during 1999-2003 on storability of Chinese cabbage cultivars, Bilko F1 had the best storability. After storage at 0 and 2 °C, the highest percentage of marketable material and the lowest percentage of chilling injury were noted for cultivar Bilko F1. Storability of Morillo Storido F1 cultivar was slightly worse and cultivars Parkin F1 and Brocken F1 were the worst. There were differences in the storability of cabbage harvested at various dates. The best storability was for cabbage harvested at the second date i.e. when the heads were compact and the plants had shown no symptoms of senescence. Differences in cabbage storability in subsequent years resulted from variation in weather conditions during growth and ripening of heads. The cabbage harvested immediately after a period of warm weather mean temperature higher than 15 °C) was very susceptible to browning of inner midribs during storage at 0 °C. Heads collected after a colder period (mean temperature 6-10 °C) were more resistant to browning of inner midribs and had better storability.
