“…This assumption is further strengthened by the research of Minarni et al 13 which states that Dendrobium has a higher level of resistance to ORSV compared to P. amabilis based on data on the amount of chlorophyll. Minarniʼs research did not use mycorrhizal induction.…”

“…Inoculation is done gently in the direction of the leaf bone with your fingers or a cotton bud. The orchids were then reared in sterile moss growing media and observed for infection symptoms including necrosis, chlorosis, streak yellowing, mosaic, leaf malformations and leaf curling during the incubation period until these symptoms appeared 1,[10][11][12][13] .…”

Background and Objective: Phalaenopsis amabilis and Dendrobium discolor are orchids that are widely cultivated in Indonesia. Orchid cultivation has several problems, one of which is infection with Odontoglossum ringspot virus (ORSV). Rhizoctonia can be used in the induction of orchid resistance by triggering lignification in roots and leaves. However, there is little information about the induction of mycorrhizal resistance. It is necessary to study to determine of orchids resistance to virus through analysis of anatomical character on root and leave. Materials and Methods: Factorial block random design. The factor I: Orchids types: P. amabilis (A1) dan D. discolor (A2). Factor II: Inoculation treatment: Control (K), Mycorrhiza (M), Virus (V) and Mycorrhiza-Virus (MV). Parameters observed were root anatomical structure includes lignification and the presence of peloton and leaf anatomical structure includes leaf damage and thickness. Results: All types of experimental plants experienced root and leaf tissue damage due to virus inoculation and mycorrhiza. The anatomy of the treated roots had differences in the thickness of the epidermal lignin and the thickness of the carrier bundle lignin. Meanwhile, changes in the anatomical character of leaves as a result of virus inoculation showed damage to the epidermis and stomata tissue. Conclusion:Based on the anatomical observations of roots and leaves, D. discolor was more resistant to ORSV infection than P. amabilis.The results of this study become a recommendation for the types of orchids cultivated in ORSV endemic area.

“…Pengamatan gejala penyakit pada anggrek Phalaenopsis amabilis dan Dendrobium discolor hasil inokulasi ORSV selama kurang lebih 30 hari menunjukkan adanya variasi gejala infeksi, yaitu klorotik, mosaik, nekrotik, malformasi daun, streak, dan ada yang tanpa gejala. Inokulasi virus dilakukan secara mekanis menggunakan inokulum Nicotiana tabacum bergejala klorotik dan mosaik yang diketahui terinfeksi ORSV (Minarni et al, 2021). Pada penelitian ini, gejala khas infeksi ORSV yang muncul yaitu klorotik, mosaik, nekrotik, malformasi daun, dan streak sama seperti gejala yang dilaporkan pada penelitian sebelumnya (Mahfut & Daryono, 2020;Minarni et al, 2021).…”

Anggrek sangat terkenal karena memiliki corak, bentuk, ukuran, dan warna bunga beranekaragam. Phalaenopsis dan Dendrobium termasuk jenis anggrek yang diminati sehingga produksinya perlu ditingkatkan secara kuantitas maupun kualitas. Adanya infeksi virus Odontoglossum ringspot pada anggrek menjadi salah satu kendala dalam budidaya anggrek. Odontoglossum ringspot virus (ORSV) merupakan virus yang banyak menginfeksi anggrek dan menimbulkan gejala pada bagian daun berupa mosaik, nekrosis, klorotik, kelayuan serta daun menggulung. Upaya pengendalian infeksi ORSV dapat memanfaatkan mikroorganisme, seperti Rhizoctonia yang akan berasosiasi dengan perakaran anggrek membentuk simbiosis mutualisme yang kemudian dapat menyediakan nutrisi bagi anggrek. Tujuan penelitian ini adalah untuk mempelajari respon anggrek Phalaenopsis amabilis dan Dendrobium discolor terinduksi Rhizoctonia terhadap infeksi ORSV. Penelitian dilaksanakan dengan Rancangan Acak Lengkap (RAL) faktorial menggunakan 6 perlakuan dan 4 ulangan. Hasil penelitian menunjukkan bahwa Phalaenopsis amabilis lebih rentan terinfeksi ORSV daripada Dendrobium discolor, dengan gejala yaitu daun mosaik, nekrotik, dan malformasi pada kisaran waktu 11 hari setelah inokulasi dengan Rhizoctonia . Hal ini mengindikasikan bahwa inokulasi Rhizoctonia pada Dendrobium discolor yang terinfeksi ORSV memberikan ketahanan yang lebih baik dibandingkan pada Phalaenopsis amabilis.
