Karakterisasi Secara Morfologis Dan Fisiologis Isolat Ganoderma Spp. Dari Perkebunan Kelapa Sawit Rakyat Di Kabupaten Kampar
ABSTRACT
Palm oil is one of the plantation commodities that has an important role in the
economy in Indonesia. One of the causes of the decline in oil palm production in Raiu
Province is stem rot disease (BPB) caused by the pathogen Ganoderma spp. This study aims
to examine the morphological and physiological diversity of Ganoderma spp. from
smallholder oil palm plantations in Kampar Regency. This study used a descriptive method
consisting of 2 stages, namely morphological characterization and physiological
characterization consisting of: 1). Sampling of the fruiting bodies of Ganoderma spp. 2).
Identification of the fruiting bodies of Ganoderma spp. 3). Isolation of the fruiting bodies of
Ganoderma spp. 4) Purification of Ganoderma spp. 5) Somatic incompatibility test of
Ganoderma spp. 6) Identification of Ganoderma spp. 7) Lignolytic enzyme test for
Ganoderma spp. 8) Cellulolytic enzyme test for Ganoderma spp. The results of the study
were morphologically six fruiting bodies of Ganoderma spp. have differences based on
characteristics. The somatic incompatibility test of six isolates showed that there was a
separation zone between the isolates of Ganoderma spp. LPTUNRI-Gan006 isolate showed a
higher growth rate and average growth rate than other isolates. Microscopically all
Ganoderma spp. isolates. indicates the presence of a clamp connection. Six isolates of
Ganoderma spp. Physiologically capable of producing lignolytic enzymes with the formation
of clear zones and cellulolytic index values varying from 0.12 to 0.28. LPTUNRI-Gan006
isolate showed the highest ability to degrade lignin and cellulose.
