“…Oil palm is an important perennial crop in Malaysia, being the largest producer and exporter of palm oil currently (Sumathi et al, 2008), requires an efficient control methodology to manage the disease effectively. The infection occurs via the roots in close proximity to an infection source, e.g., the infected stump of a felled tree (Sanderson, 2005). Historically, control of BSR involved cultural techniques such as mechanical and chemical control; however, these techniques have no demonstrable effects (Susanto et al, 2005).…”

Symbiotic interaction of endophytic bacteria with arbuscular mycorrhizal fungi and its antagonistic effect on Ganoderma boninense

Endophytic bacteria (Pseudomonas aeruginosa UPMP3 and Burkholderia cepacia UMPB3), isolated from within roots of oil palm (Elaeis guineensis Jacq.) were tested for their presymbiotic effects on two arbuscular mcorrhizal fungi, Glomus intraradices UT126 and Glomus clarum BR152B). These endophytic bacteria were also tested for antagonistic effects on Ganoderma boninense PER 71, a white wood rot fungal pathogen that causes a serious disease in oil palm. Spore germination and hyphal length of each arbuscular mycorrhizal fungal (AMF) pairing with endophytic bacteria was found to be significantly higher than spores plated in the absence of bacteria. Scanning electron microscopy (SEM) showed that the endophytic bacteria were scattered, resting or embedded on the surface hyaline layer or on the degraded walls of AMF spores, possibly feeding on the outer hyaline spore wall. The antagonistic effect of the endophytic bacteria was expressed as severe morphological abnormalities in the hyphal structures of G. boninense PER 71. The effects of the endophytic bacteria on G. boninense PER 71 hyphal structures were observed clearly under SEM. Severe inter-twisting, distortion, lysis and shriveling of the hyphal structures were observed. This study found that the effect of endophytic bacteria on G. intraradices UT126 and G. clarum BR152B resembled that of a mycorrhiza helper bacteria (MHB) association because the association significantly promoted AMF spore germination and hyphal length. However, the endophytic bacteria were extremely damaging to G. boninense PER 71.

“…This is in line with the roots of mature oil palm tree which can spread up to four planting rows resulted in frequent root contacts (Miller et al, 1999). However, the root to root spreading were not fully accepted as the only mode of spreading of the disease as there are also possibility that it would be spread by basidiospores which were produced and released by fruiting bodies or sporophore (Miller et al, 1999;Sanderson et al, 2000;Sanderson, 2005). However, the spread by spore might not be the major cause of BSR infection in the field.…”

Basal Stem Rot (BSR) is a disease caused by fungus which affect oil palm tree. This study aims to visualize the geographical distribution of BSR incidence among oil palm smallholders in Selangor using Geographical Information System (GIS) and its relationship to the type of soil series. The geographical distribution of BSR incidence of smallholders in Selangor were mapped using 168 Global Positioning System (GPS) coordinate of possible infected area. The methodology followed in finding the relationship between BSR and soil series by assigning percentage of BSR incidence based on type of soil series. Majority of the BSR incidences were found to be confined to the Selangor-Kangkong (Aeric Tropic Fluvaquent-Typic sulfuric tropic fluvaquent) soil series followed on Peat (Typic Fibric Tropohemist) soil then Kranji (Typic Sulfaquents) soil series and finally the Briah-Organic Clay and Muck (Typic Tropic Fluvaquent) soil series. Distribution pattern of the BSR revealed that most of the incidences were confined along the coastal area which might be due to the planting of oil palm in previous coconut stands. Low pH of Selangor (Aeric Tropic Fluvaquent) and Peat (Typic Fibric Tropohemist) soil series shows a higher BSR incidence while high pH of Kranji (Typic Sulfaquents) and Briah (Typic Tropic Fluvaquent) soil series shows slightly lower BSR incidence. From this study, it can be concluded that the distribution of BSR were mostly confined to the coastal areas which might be due to the planting of oil palm in previous coconut stands rather than any relationship with the type of soil series. This distribution map of BSR incidence can be used to deliver effective extension services regarding BSR to smallholders with a specified target based on location and soil series.

“…However, despite mass production of basidiospores in oil palm plantations, the basidiospores have insufficient inoculum potential to directly infect living oil palm. Sanderson (2005) indicated that Ganoderma basidiospores in oil palm fields may originate from several sources. The basidiospores may originate from basidiocarps formed on felled coconut trunks and stumps in oil palm fields which were previously coconut fields, and from basidiocarps growing on felled oil palm and infected oil palm.…”

Pathogenicity tests were carried out on oil palm seedlings and germinated seeds using monokaryotic and dikaryotic mycelia in order to investigate the indirect role of basidiospores in initiating basal stem rot disease in oil palm. The pathogenicity tests conducted showed that monokaryotic mycelia were not able to cause infection while reconstituted dikaryotic mycelia could initiate basal stem rot infection on both oil palm seedlings and germinated seeds. The severity of the disease symptoms on both seedlings and germinated seeds was found to be related to the size of the inoculum, with larger inoculum resulting in more severe symptoms. The present study indicates that monokaryotic mycelia which originated from germinating basidiospores could colonise any available substrate and that basidiospores therefore indirectly played a role in basal stem rot infection in oil palm fields.
