Basal Stem Rot BSR incidence caused by Ganoderma boninense is the most serious disease in South East Asia;s oil palm industry particularly in Malaysia and Indonesia. The total area planted with oil palm has been increasingly infected by this disease and caused many concerns within the industry. To date there is no promising remedy or reliable detection technique for this disease is confidently reported. Therefore this study has been carried out to evaluate the level of partial resistant and susceptibility among different commercial oil palm progenies against BSR caused by G. boninense. Plant materials with the age of a sixteenth month-old of four different progenies with different genetic background of oil palm seedlings consisting of uninoculated seedlings served as control and inoculated seedlings with G. boninense colonized rubber wood blocks were screened for the differences. Nine months after inoculation palms were harvested and symptoms were evaluated based on disease incidence disease severity ergosterol content and re-isolation of infected root segments on Ganoderma Selective Medium GSM for further confirmation. Palms severely infected with G. boninense showed a higher disease incidence disease severity and ergosterol concentration. However there is no ergosterol detected and disease incidence and severity did not occur for all uninoculated oil palm progenies seedlings. Various progenies also showed dissimilar results in terms of ergosterol concentration disease incidence and disease severity depends upon their level of partial resistant and susceptibility. This finding has provided valuable information for the subsequent experiment to be conducted on screening for antimicrobes detection of specific volatile and non-volatile compounds that can be used to indicate the presence of BSR in oil palm plantations.

Abstract

Basal Stem Rot BSR incidence caused by Ganoderma boninense is the most serious disease in South East Asia;s oil palm industry particularly in Malaysia and Indonesia. The total area planted with oil palm has been increasingly infected by this disease and caused many concerns within the industry. To date there is no promising remedy or reliable detection technique for this disease is confidently reported. Therefore this study has been carried out to evaluate the level of partial resistant and susceptibility among different commercial oil palm progenies against BSR caused by G. boninense. Plant materials with the age of a sixteenth month-old of four different progenies with different genetic background of oil palm seedlings consisting of uninoculated seedlings served as control and inoculated seedlings with G. boninense colonized rubber wood blocks were screened for the differences. Nine months after inoculation palms were harvested and symptoms were evaluated based on disease incidence disease severity ergosterol content and re-isolation of infected root segments on Ganoderma Selective Medium GSM for further confirmation. Palms severely infected with G. boninense showed a higher disease incidence disease severity and ergosterol concentration. However there is no ergosterol detected and disease incidence and severity did not occur for all uninoculated oil palm progenies seedlings. Various progenies also showed dissimilar results in terms of ergosterol concentration disease incidence and disease severity depends upon their level of partial resistant and susceptibility. This finding has provided valuable information for the subsequent experiment to be conducted on screening for antimicrobes detection of specific volatile and non-volatile compounds that can be used to indicate the presence of BSR in oil palm plantations.
