Various ORSV infection symptoms on ceratorhiza induction in orchid plants

Several types of orchids that are in great demand and cultivated by various groups Phalaenopsis sp. Dendrobium Mycorrhizae needed orchid plants to complete their life cycle. This is because mycorrhizae capable symbiosis with the root system host plant so plant's capacity absorb elements will increase. study aims determine extent which Ceratorhiza induction on amabilis discolour can suppress symptoms Odontoglossum ringspot virus (ORSV) infection. The method used this was a factorial completely randomized design (CRD) 2 factors 4 replications. first factor type used, namely (A1) (A2), while second administration mycorrhizae, viruses, mycorrhizal viruses. Observation disease done looking at appear leaves have been infected ORSV. results showed appeared were form mosaic, necrosis, leaf malformation, mosaic necrotic. not able infection based obtained; treatment inoculated viruses more severe compared only increased response discolours decreased length, width, number. Meanwhile, organ, an length number roots.
