Creation of a new bio-energy that will not compete with food production : development of sago palm as a new resource in Melanesia

在巴布亚新几内亚北部的东塞皮克，西米棕榈树的民间变种根据植株的大小进行了分类，并以其名称反映了其形态特征。同样在新爱尔兰岛的凯文，民间品种的名称与植物特性有关。此外，还发现了一个树干明显粗大的民间品种，可能是一个高产品种。在印度尼西亚新几内亚岛的西巴布亚，节间长度与胸径呈负相关趋势。髓中淀粉含量与节间长度呈负相关，说明生长速度较快的民间品种可能是低产品种。

In East Sepik of northern Papua New Guinea, folk varieties of sago palm were classified based on size of plant body and the morphological characteristics were reflected as their name. Also in Kevien of New Ireland Island, the name of folk varieties was related with plant characteristics. Moreover, a folk variety that had an apparently thick trunk was found, and this folk variety might be a high yielding variety.In West Papua on Indonesian territory of island of New Guinea, a tendency of negative relationship between the internode length and diameter breast height was found. The other negative relationship between the internode length and starch concentration in pith was found, which meant folk varieties that shows comparatively higher growth rate may be low yielding varieties.
