ABSTRACT

Orchids are infected by many plant viruses among which Cymbidium mosaic virus (CymMV) is the most prevalent virus. In Kerala, the virus was detected in almost all orchid growing nurseries with varying severity. Commonly observed symptoms of CymMV included irregular mottling and mosaic patterns on leaves. The presence of this virus was confirmed by using DAC-ELISA using specific antibody of CymMV. It was confirmed by TEM analysis to show flexuous rod shaped particles of 400- 1000nm, which is the characteristic feature of Potex viruses in general. The plants were found to acquire disease through mechanical means as the virus is highly mechanically transmissible. Production of virus free plants using meristem culture was followed as other treatment technique fail to cure the disease effectively and without involving high cost.
Keywords: CymMV, Dendrobium sp., DAC-ELISA, Meristem culture, Vulnerability index.
