Revaluation of production potential of palms as a crop for bioethanol.

通过查阅和文献调查，在一千多种棕榈科植物中，以糖为原料的棕榈有19种，以淀粉为原料的棕榈有16种。在制糖棕榈方面，研究了4种被认为具有高生产潜力的棕榈（糖棕榈、椰子树、棕榈和棕榈），结果表明，从它们中生产生物乙醇是无利可图的，尽管从它们中获得了大量的糖液。然而，只有棕榈具有潜在的生物乙醇作物，因为它们的汁液可以以较低的价格收集，其花序位置较低。关于淀粉棕榈，西米棕榈被认为是一个有吸引力的候选生物乙醇作物，因为它具有极高的淀粉产量。

As results of inquiring and bibliographic surveys, in more than one thousand species of palmae plants there were 19 and 16 species of palms for sugar and starch, respectively. Regarding palms for sugar, 4 species (sugar palm, coconut palm, palmyra palm and nypa palm) , which was thought to have high production potential, were researched with respect to its sugar production, resulting that producing bioethanol from them were unprofitable, though a large sugar sap was obtained from them. However, only nypa palm has potential for a bioethanol crop because their sap could be gathered at a low price for its low position of inflorescence. Regarding palms for starch, sago palm was considered to be an attractive candidate of bioethanol crop due to extremely high starch production.
