| Outline of Final Research Achievements |
The biomass, total sugar and starch contents of each part of shoot (above-ground part of plant) of four starch accumulating palms in the Tropics, sago palm (Metroxylon sagu), sugar palm (Arenga pinnata), ”sagu baruk”(Arenga microcarpa) and gebang palm (Corypha utan) were measured and ethanol efficiency from each part were determined. Biomass, total sugar and starch contents of each part of shoot in all the palms were higher in the order of pith>> bark≧ petiole + leaf sheath> leaflet> rachis and the percentage of pith was 39～75%, 52～72%, 88～98%, respectively. The ethanol efficiency of each part of shoot of these palms ranged from 1.5 to 98.2ml/100g dry weight. Consequently, the estimated ethanol amount produced from pith of these palms (57～1293L) contributed 77～96% of whole the ethanol amount from the shoot. From these results it was recommended to use the only pith part of these palms for ethanol production.
