Abstract
The study was conducted from 1999 to 2002 in the Pomology Department of the Agricultural University in Lublin. The experimental materials were hazelnut trees of cv. ‘Olbrzymi z Halle’, ‘Kataloski’ i ‘Webba Cenny’ planted in 1989 at the distance 4 × 3 m. The fruit size distribution, mass of single nut and kernel and content of water were evaluated immediately after harvest and after 8 weeks of storage. In addition, in 1999–2001 total content of oil, content of linoleic acid and content of major nutrients (N, P, K, Ca, Mg) were determined. The significant differences in the size nuts and values of examined features between cultivars were found. The content of water in dried kernels varied depending on cultivars from 3,79% to 4,08%. The loss of fruit mass during 8 weeks of drying kernels was from 27,5% to 29,6%. The best quality among studied cultivars had cv. ‘Olbrzymi z Halle’.
