Résumé

The effect of organic growing was studied on the storability of apples cv. Jonica, Liberty, Mutsu and Pinova. Fruits from integrated and organic orchards were stored at 2-4 °C, with 95-99% relative humidity for 6 months. Firmness, beta-galactosidase activity and polygalacturonase enzymes were examined. There was no difference in the activity of beta-galactosidase and polygalacturonase enzymes at harvest between the organic and integrated apples, but a significant difference was noted between the cultivars, with the exception of Mutsu and Pinova. Beta-galactosidase activity increased significantly during storage with the exception of cv. Pinova and polygalacturonase activity also increased significantly. The difference in the polygalacturonase activity became significant between the cultivars during storage with the exception of cv. Jonica and Pinova. The firmness decreased significantly during storage, with the least change in the case of cv. Jonica and Pinova. It can be established that there is, in general, neither a considerable difference between the growing systems nor between varieties at harvest. The differences became greater during storage. It can be stated that the effect of cultivar on storability is much more considerable than the effect of the growing system.
