The effects of Cymbidium mosaic virus and Odontoglassum ringspot virus on the growth of Cymbidium orchids

Two cultivars of Cymbidium orchid were mechanically inoculated with Odontoglossum ringspot virus (ORSV) and Cymbidium mosaic virus (CyMV), individually and in combination. ORSV was found to have an infection rate of 70 per cent (as determined by ELISA), but seldom induced easily discernable leaf sym...

Summary:Two cultivars of Cymbidium orchid were mechanically inoculated with Odontoglossum ringspot virus (ORSV) and Cymbidium mosaic virus (CyMV), individually and in combination. ORSV was found to have an infection rate of 70 per cent (as determined by ELISA), but seldom induced easily discernable leaf symptoms. CyMV had an infection rate of only 20 per cent, but infected plants invariably produced a pronounced leaf mosaic either with or without necrotic streaks. Both viruses were found to reduce plant growth, the effects of CyMV being more severe than those of ORSV.
