PRUNE DWARF VIRUS IN PRUNUS AVIUM L. AFFECTED BY FLAT LIMB AND STEM PITTING |
| Authors: | F. Gualaccini, M. Barba |
| Abstract:
Graft transmission and sap inoculation tests were carried out from sweet cherry trees affected by flat limb and stem pitting or by stem pitting alone. Stem pitting and flat limb symptoms were reproduced, respectively, in two and one sweet cherry seedlings out of five that had been graft-inoculated. From all naturally infected trees a virus with quasi-isometric particles was isolated which, based on host range responses, behaviour during purification, serology and electron microscopy, was identified as an isolate of prunus dwarf virus. | |
