Abstract:
Within the survey of the health conditions of park and habitation greenery a virus disease of two cultivars Rumba and Cardinal was revealed.
Biological and serological tests confirmed the sour cherry necrotic ringspot virus.
The virus from diseased leaves and pollen of roses was positively mechanically transmitted on the tested plants: Cucumissativus L., Cucurbita maxima cv.
Reisen Melonen Gelber, Chenopodium quinoa Willd., Momordica balsamina L. From serological tests we have obtained a positive reaction using the dropping precipitation reaction and the difuse agar-gel test, as well as the antiserum against the sour cherry necrotic ringspot virus prepared from our own virus isolate and the antiserum obtained from Dr.
Fulton.
