The woodiness virus of the passion vine (Passiflora edulis Sims.)

Abstract

Studies on the epiphytology, symptomatology and transmissibility of the woodiness virus are reported. Greenhouse and field studies have shown 13 distinct symptoms to be associated with the virus. These are described. It is postulated that the woodiness virus as it occurs in Australia exists as a complex of strains and is not a single entity, as previously thought.
