Fungal Community Inhabiting Hevea brasiliensis Organs and Soil

Abstract

Abstract Rubber ( Hevea brasiliensis Mull.Arg.) is one of Indonesia’s largest commodities that is widely managed by farmers. The rubber plantation sector is experiencing declining production due to climate change and is more vulnerable to plant-disruptive organisms. Diseases of rubber plants are leaf fall, white root fungus, and odium powdery mildew caused by microbes, more precisely fungi. The purpose of this study was to identify the diversity of fungal genera on the leaves, bark, roots, and soil of rubber plants by stratified dilution isolation methods and direct isolation (surface sterilization). The study showed that the number of fungus isolates that were successfully isolated was 101 isolates. There is a significant difference between the number of isolates in the organs and soils of rubber plants. However, it does not differ significantly between the number of isolates on the leaves, bark, and roots of rubber plants. The genus of fungi is included in Penicillium sp., Aspergillus sp., Gliocladium sp., Trichoderma sp., Cylindrocladiella sp., Cunninghamelle sp., Rhizoctonia sp. Gongronella sp., Paecilomyces sp., and Mucor sp.
