摘要: Summary Analyzing the results of virus indexing ornamental cherries and plums, purpleleaf sand cherry ( Prunus × cistena (Hansen) Koehne) proved to be a natural host necrotic ringspot (PNRV). PNRV-infected P. shrubs showed neither growth abnormities nor foliage symptoms or any other disease appearances. The PNRV tolerance interspecific hybrid seems derived from plum cerasifera Ehrh.), one both parental species.
