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

通过调查和文献调查，在1000多种棕榈科植物中，含糖棕榈树有19种，含淀粉棕榈树有16种。关于制糖棕榈树，研究了被认为具有较高生产潜力的4种棕榈树(糖棕榈树、椰子棕榈树、Palmyra棕榈树和NYPA棕榈树)的产糖量，结果表明，利用它们生产生物乙醇是无利可图的，尽管它们获得了大量的糖液。然而，只有NYPA棕榈树具有生物乙醇作物的潜力，因为它的花序位置低，可以低价收集它们的汁液。在淀粉方面，西米棕榈由于淀粉产量极高，被认为是一种有吸引力的生物乙醇作物。

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.
