| Abstract: | The reactions of Beta procumbens C. Sm. and Beta webbiana Moq. were compared to those of Beta vulgaris L. with regard to an infection by Cercospora beticola Sacc. The fleck reaction obsrved in B. webbiana may be interpreted as hypersensitivity based on symptomatological, light microscopical, fluorescent microscopical and electron microscopical data. The B. procumbens clone was found to show resistance characteristics similar to those of B. webbiana and B. vulgaris, as it reacted both by flecks (B. webbiana) and leaf spots (B. vulgaris) to a C. beticola infection. |
