Abstract

Liwa Botanical Garden is located in West Lampung Regency which has an area of 86.6 hectares and is one of the conservation of ornamental plants that presents the flora of the Bukit Barisan Selatan National Park. One of the flagship collections of this botanical garden is a native orchid. Disease infection is still a major obstacle in the cultivation and development of native orchid potential at Liwa Botanical Garden. Based on the results of previous studies, it is known that several individual natural orchid collections from Liwa Botanical Garden showed symptoms of fungal disease infections. Disease infections can inhibit plant growth and resistance and reduce the aesthetic value periodically. Symptoms of infection include necrotic patches on the upper surface of the leaf. This research was conducted to determine the identification of diseases and efforts to protect native orchids against fungal infections at Liwa Botanical Garden through a collection of samples that showed symptoms of infection, analysis of disease symptoms, and analysis of disease resistance levels. The results showed that the response of the native orchid at Liwa Botanical Garden to fungal infections was showed symptoms of wilting in the leaves, namely in the orchids Eria sp., Dendrobium sp., and Cymbidium sp. turns black on the edge of the leaf, Thrixspermum sp. The type of orchid most commonly infected with fungus is Cymbidium sp. a total of 8 samples, and Thrixspermum sp. 3 samples, Eria sp. as many as 4 samples, Dendrobium sp. and Calanthe triplicata as many as 6 samples. The type of native orchid that is most susceptible to fungal infections is Dendrobium sp. and Eria sp. with disease intensity of 74.11% and 22.3%. The results of this activity are expected to be basic information in efforts to protect plants against diseases to support the application of conservation of native orchids on Liwa Botanical Garden.

Abstract

Anggrek memiliki nilai ekonomis yang tinggi sehingga sangat potensial untuk dibudidayakan. Jenis yang paling banyak diminati masyarakat adalah Dendrobium dan Phalaenopsis. Namun terdapat kendala utama yang dapat memengaruhi pertumbuhan anggrek yaitu infeksi virus. Jenis virus yang dilaporkan paling banyak menginfeksi adalah Odontoglossum ringspot virus (ORSV). Infeksi virus ini dapat menghambat pertumbuhan dan ketahanan tanaman, menurunkan kualitas bunga dan nilai estetika serta daya jual. Didapati pula gejala infeksi virus berupa mosaik, klorotik, streak, dan nekrosis. Salah satu upaya untuk mengatasi infeksi virus adalah dengan memanfaatkan mikoriza. Mikoriza yang dapat digunakan yaitu Rhizoctonia sp. Asosiasi mikoriza pada tumbuhan anggrek dapat memberikan pengaruh positif pada penyerapan nutrisi dan pertumbuhan inangnya, sehingga diharapkan dapat melindungi anggrek dari infeksi virus. Tujuan penelitian ini untuk mengetahui efek induksi Rhizoctonia pada karakter anatomi daun Phalaenopsis amabilis dan Dendrobium discolor yang diinfeksi ORSV dan mengetahui apakah terdapat perbedaan anatomi diantara kedua anggrek tersebut. Penelitian dilakukan di Laboratorium Botani Biologi FMIPA Unila dengan menggunakan Rancangan Acak lengkap Faktorial. Hasil dari penelitian ini adalah terdapat perbedaan ketebalan daun antara daun yang diinokulasi virus dan daun dengan perlakuan mikoriza. Daun anggrek dengan perlakuan mikoriza memiliki ketebalan tertinggi sedangkan yang terinfeksi virus memiliki ketebalan terendah.

Abstract

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.

Abstract

Orchids have a high level of biodiversity, such as Dendrobium and Phalaenopsis, which are epiphytes. Dendrobium can adapt to the condition of where it lives while Phalaenopsis can grow in highlands and depends on sunlight and humidity. Virus infection has become one of the obstacles in cultivating Dendrobium and Phalaenopsis. Efforts to increase fitness and control in Dendrobium and Phalaenopsis cultivation can be done by inducing the plant’s fitness using a mycorrhiza, such as Ceratorhiza. A mycorrhiza is a form of mutualism between fungi and the plant’s root. This research is aimed to give information related to the utilization of Cerathoriza for inducing orchids to suppress Odontoglossum ringspot virus (ORSV) infection, giving it better growth. The research was done in February-March 2021 at Botany Laboratory University of Lampung. A completely randomized factorial design was used on two factors, kind of orchid and mycorrhiza treatment (M), virus (V), and mycorrhiza virus (MV). Variables examined in this research are the amount of living and dead roots and leaves. Data obtained is homogenized using Levene’s test and continued by ANOVA with the significance level of 5% and further testing using Tukey’s test with the significance level of 5%. From this research, it is known that interaction between Phalaenopsis and Dendrobium exists during virus and mycorrhiza administration. It is concluded that Phalaenopsis anabilis is more vulnerable than Dendrobium discolor.

Abstract

Lampung Indonesia is one of the provinces on the island of Sumatra, which has a flora conservation area located in Liwa Botanical Garden, West Lampung Regency. One of the flora species in the area with a high level of diversity is the orchid plant. The Dendrobium is the largest orchid species, where the public widely hunts this orchid for an economic reason due to the beauty of its various flower shapes and colors. Given the high level of human encroachment, this can threaten the existence of natural orchid plants, causing loss of their original habitat and causing the extinction of orchid species. Based on data in Liwa Botanical Garden, there has been no further identification of natural orchids as a plant conservation effort. To protect and immediately save these natural orchids, it is necessary to identify the Dendrobium orchid species based on the leaf morphological approach. This research will be conducted in April-September 2020. Observations of leaf morphology include leaf shape, leaf tip shape, leaf base shape, leaf edge, leaf reinforcement, leaf arrangement, leaf surface texture, leaf symmetry, and leaf sitting based on guidelines for ornamental plant characterization books. Observations as secondary data were added to the character of the pseudobulb shape and orchid habitat. Observations as secondary data were added on the habitat character of pseudobulbs and orchids. The implementation of this activity is still in the period of the Covid-19 pandemic, so most of the activities are carried out online. The coaching and training phase was conducted through internal virtual discussions on Tuesday, July 7, 2020, while the coaching phase was conducted through meetings or verbal communication via telephone groups and WhatsApp. Based on the evaluation data, it is known that there is an increase in knowledge and understanding of training participants by 21.64 points. The percentage increase in value before and after training is 34.72%. Orchid-related activities at Liwa Botanical Garden were never carried out, thus imparting knowledge to Liwa Botanical Garden technicians and workers on the development of natural orchid identification methods based on the morphological character in local natural resource conservation in the 4.0 industrial revolution era.
