First report of Chrysanthemum stunt viroid in Slovenia
In August 2009, samples of chrysanthemums (Dendranthema x morifolium) from a glasshouse crop located in the western part of Slovenia were sent to the laboratory for testing. Twelve out of 200 chrysanthemum plants (cv. ‘Miral’ originating from Germany) showed viroid-like symptoms (stunting and yellow leaf spots). It was observed that within the affected glasshouse, these symptomatic plants were randomly distributed. Results of the analysis (PCR assays, biological tests) confirmed the presence of Chrysanthemum stunt viroid (Pospiviroid, CSVd – EPPO A2 List). This is the first time that CSVd is reported from Slovenia.
The situation of Chrysanthemum stunt viroid in Slovenia can be described as follows: Present, detected in glasshouse chrysanthemums in 2009.
