Odontoglossum ringspot virus(ORSV) is a orchid virus which infection most widely reported and has spread widely in the world, including in Indonesia. Viral infections candegrade the quality of the orchid plant so it is economically detrimental. The early stages ofdisease control can be done through the introduction of infection symptoms that appear.This research was conducted to study the response of some plant oforchid (Orchidaceae)against a single infection of ORSV trough mechanical inoculation. Futhermore, virusdetection on orchid tissue was done trough the DAS-ELISA and RT-PCR.The resultsshowed that Pectelis sussanae(L.) Raf. was the only orchid plant that was immune againstORSV approached.Dendrobiumsp.,Cymbidiumsp.,Chattleyasp.,Phalaenopsissp.,andSpathoglotis sp. showed a response of susceptible of ORSV severe infection symptoms,while Liparis sp. were resistant. The variation of resistance from several orchid plantagainst infection ORSV showed severe symptoms with the incubation periodewas seenearlier.The observation of virus structureusing TEMshowed rigid road shape particle, 300x 18 nm in size, which is general characteristic ofTobamovirus.This indicate an infectionof ORSV is a dangerous disease and require serious control.
