Abstract

Liwa Botanical Garden is located in Balik Bukit Subdistrict, West Lampung Regency, is a mountainous area surrounded by hills with a slope of 10% - 40%. This botanical garden has one of its superior collections namely native orchids. Based on the results of previous studies, it is known that several native orchid individuals at Liwa Botanical Garden show symptoms of being infected with a mixture of viruses, bacteria and fungi. Mixed infections will show more severe symptoms than single infections. This study was conducted to determine the identification of diseases and efforts to protect native orchids against mixed 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 the response of native orchids at Liwa Botanical Garden to mixed infections showed symptoms in the form of necrosis, streak, chlorotic, soft rot, and fungal spots on the orchid Ascideria longifolia, Polisthacia sp., Bulbophyllum sp., Calanthe tripicata, and Eria sp. The type of orchid that shows the most symptoms is Bulbophyllum sp. a total of 8 samples. The type of native orchid that is most susceptible to mixed infections is Eria sp. with a disease intensity of 32.7%. 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 at Liwa Botanical Garden.
