TRANSLOCATION OF CHERRY LEAF ROLL VIRUS (CLRV) IN JUGLANS REGIA
In 1993 we started a study of CLRV translocation evolution in Persian walnut using the ELISA-DAS technique. In May, one year old virus-free seedlings were budded with infected patch with or without bud. The use of infected buds was clearly the most effective way for speeding the inoculation. CLRV was present in the whole plant from the top to the roots. In plants inoculated by patch bark without bud, the virus remained close to the inoculation site after two years.
