Abstract

Basal stem rot which is caused by Ganoderma boninense is the most serious disease faced by oil palm Elaies guineensis in Malaysia. The study was conducted to investigate any potential antimicrobial properties in E. guineensis roots after elicitation by UV radiation and any antagonist activity of Aspergillus niger against Ganoderma boninense. In vitro antagonistic activity assays by using dual culture technique was done to test the antagonistic activity of Aspergillus niger to Ganoderma boninense. The result did not show any antagonism of Aspergillus niger against Ganoderma boninense. Twenty oil palm seedlings roots were used and 140g of oil palm roots were elicited by UV light with 254nm. The plant material from elicited oil palm root with different concentration 0.86mg/μl,0.83mg/μl, 0.96 mg/μl and 0.85 mg/μl) was extracted. The paper disc diffusion method was used to screen antimicrobial. activity of the extracts. The acetone extracts were loaded on each paper disc (6mm) and air dried to evaporate the acetone. Then, the tested microorganism is Aspergillus niger. The result showed no inhibition zone around the discs. This indicates that there was no antimicrobial compound present in the crude extracts. Insufficient concentration of any potential antimicrobial compound from the crude extracts caused the failure of crude extracts to show a promising antimicrobial activity. The study did not show any antagonistic activity of Aspergillus niger against Ganoderma boninense and no antimicrobial compound was present in the crude extract.
