Reaction of selected celeriac varieties to infection by Cercospora apii.

摘要

Twenty two celeriac cultivars were tested in a field experiment for reaction to Cercospora apii based on disease severity, fresh weight reduction of leaves and roots. All tested cultivars were susceptible to infection and disease occurrence and had substantial influence on evaluated parameters. On average, infected plants produced only 26% and 44% of leaf and root mass comparatively to the control consisting of healthy plants.
