摘要：
The accumulation of potato virus Y(o) (PVY(o)) and potato leaf roll virus (PLRV) was studied in plants of Solanum brevidens co-infected with each of six viruses or a viroid. Virus could not be detected by ELISA in plants of S. brevidens infected solely with PVY. However, accumulation of PVY was increased c. 1000-fold in plants doubly infected with tobacco mosaic virus or potato spindle tuber viroid (PSTVd). PVY titres in doubly infected plants of S. brevidens were between 1% and 0.1% of those found in the PVY-susceptible interspecific Solanum hybrid DTO-33. Double infections of S. brevidens by PVY and alfalfa mosaic virus or potato viruses M, S, T or X did not significantly enhance PVY accumulation. Accumulation of PLRV was not enhanced in plants co-infected with any of the six viruses or PSTVd.
