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