Establishment of systemic or localised infection, or failure to establish infection, in 15 native plant species inoculated with introduced and indigenous viruses.

For an explanation of virus acronyms and isolates see Table 1. Sap inoculations used, except aphid inoculation used with BYDV and TuYV, and sap, aphid and graft inoculation all used to inoculate H. comptoniana with HarMV. Grafting also used to inoculate AMV, BYMV-MI, BYMV-FB1, CMV-SN, CMV-LW, PaVY-KnxP-1, PaVY- KnxP-1, PSbMV and PVX to H. comptoniana. Virus detection in leaf samples from inoculated or non-inoculated leaves was by ELISA. Samples from inoculated or tip leaves were grouped separately initially for each virus-plant species combination, but if virus infection was detected each sample was tested individually.
