Oil Palm (Elaeis guineensis Jacq.) Bunch Structure Variation and Limitations

HENDERSON, William. J., PURBA, Olivia., PURBA, Hanna Immanuella, TJEUW, Juliana.

Abstract: Palm oil quality and quantity are dependent on fruit ripeness. In normal oil palm bunch development when the outer fruit are mature, inner fruit are still at earlier stages of development and maturation. While this variation and lack of maturation synchrony might be an acceptable evolutionary development, it is a major constraint to commercial production. Normal and abnormal bunch structures were investigated to determine their effects on yield. Substantial quantities, 38 - 81% of fruit produced did not reach maturity, and in one case 50% of fruit were not pollinated. This results in lost yield and wasted resources. By providing bunch structures conducive to equal fruit maturation, commercial yields could increase substantially, in excess of 100% in some cases. Palms with different or more open structures should be identified, assessed and the genes responsible identified. Development of bunch structures similar to those of date palm (Phoenix dactylifera L.) and sugar palm (Arenga pinnata (Wurmb) Merr.) should be investigated as they would provide unlimited fruit developmental space and allow maturation synchrony.
