Sažetak
Celeriac quality components are influenced by cultivars, growing methods, climatic factors and soil quality.
Muck soils of the Vrana area and long growing period as a result of the Mediterranean climate are favorable for celeriac production.
Two years experiment was conducted with 3 cultivars: Nemona, Volltreffer and Praški orijaš planted in 2 row distance and 3 bend with 8.3, 10.0, 11.1, 12.5, and 13.3 plants/m2 respectively and 5 replications.
During harvest following quality components mean root weight and mean weight were investigated After classification according to diameter (6-8, 8-10 and >10cm), incidence of internal holes (>1 cm) and the dry matter content (Brix) were established.
According to ANOVA, mean root weight there were no significant differences between cultivars and spacings (Volltreffer 374 g, Nemona 334 g and Praški orijaš 319 g). With the increase of the number of plants/m2 the root mean weight slightly decreased (370 to 259 g). The lowest percentage of small roots was found in Volltreffer 23.5 %, at Praški orijaš 31.0 % and Nemona 40.5 %. With the increase of the number of plants/m2 the percentage of small roots increased too (from 26.5 to 39 %). Mean weight of small roots was 208 to 249 g, medium 366 to 398 g and large 586 to 653 g. Praški orijaš had the smalest mean weight in all sizes. With spacing decrease mean weight in all sizes slightly decreased.
In the first year experiment more internal were was found than in the second year which suggests the influence of climatic factors. More internal holes were found in larger roots than in smaller categories. The same tendency was shown with larger spacings. The dry matter content was from 5 to 7 %. The highest values were found in Praški orijaš cultivar.
According to presented experimental results it is not possible to suggest the best cultivar and planting method in respect to quality components.
