项目摘要

The field surveys were conducted for Metroxylon warburgii on Espritu Santo and Malakura, Vanuatu in 2002,M.vitiense and M.warburgii on Vanua Levu and Viti Levu, Fiji in 2003 and M.waburgii and M.paulcoxii (M.upoluense before 1998) on Upolu, Samoa in 2004. Considering the results of M.salomonense and M.warburgii on Gaua, Vanuatu in 2000 and of M.amicarum on Moen, Uman and Pohnpei, Micronesia in 2001,the starch yield of palms of genus Metroxylon section Coecoloccus that are distributed southern and western Pacific in was low in comparison with M.sagu (namely sago palm) of section Metroxylon (Eumetroxylon) that is distributed in Southeast Asia and Melanesia. The low starch yield of the palms of section Coelococcus was attributed for some factors as follows : comparatively small size in M.warburgii, low dry matter percentage of pith and low starch content in pith in all species (In M.paulcoxii, the palm size was small, but the yield components were not measured because only one individual was found). However, the total sugar content in pith was higher in palms of section Coelococcus that in M.sagu. These were considered to be related with some characteristics : M.sagu is mainly propagated by the suckers and produces seeds that show very poor germinability, and the palms of section Coelococcus do not produce any suckers produce seeds that show very high germination percentage.

2002年在瓦努阿图的Espritu Santo和Malakura进行了实地调查，2003年在斐济的瓦努阿卢和Viti Levu进行了Vitiense和M.warburgii的实地调查，2004年在萨摩亚的Upolu进行了Waburgii和M.paulcoxii(1998年以前的M.upoluense)的实地调查。考虑到2000年在瓦努阿图的戈阿和2001年在密克罗尼西亚的莫恩、乌曼和波恩佩发现的沙门氏支原体和华氏支原体的结果，与分布于东南亚和美拉尼西亚的密克罗尼西亚支原体(Eumetroxylone)的萨古支原体(M.sagu)相比，分布在太平洋南部和西太平洋的椰子属棕榈树的淀粉产量较低。瓦氏腔球菌组果肉淀粉产量较低的原因是：各树种的果肉体积较小，髓干物质含量低，果肉淀粉含量低(泡桐果肉较小，但由于只有一个个体，所以没有测量产量构成因素)。然而，腔球菌组的棕榈髓中总糖含量却高于麻疯组。认为这与黄瓜的一些特性有关：黄瓜主要由吸盘繁殖，产生的种子发芽率很低，而腔球菌组的手掌不产生任何吸盘，产生的种子发芽率很高。
