项目摘要

The purpose of this research program is to analyze how wood structure and other morphological characters of trees are changed with elevation of altitude in Himalayan region. For this purpose, two field research were done during the term of this program, During these field researches, plant specimens were collected and dried as herbarium specimen, small cubic blocks of wood and bark were cut off from erect trees using saw, chisel and hammer with their voucher herbarium specimens.1.Field research in 1994. June 1,1994-September 10,1994. Area : Mt. Manaslu and Mt. Annapurna region, Central-West Nepal. Route : Kathmandu-Trisuli Bazar-along Burigandaki-around Ganeshu Himal-Larkya La(alt.4900m)-along Dudhu Khora-along Marsyanagdi Hhora-Thorung Pass (alt.5110m)-along Kali Gandaki-Pokhara-Kathmandu(about 45 days).Collection : about 18,000 sheets of herbarium specimens, about 780 wood samples, about 490 bark samples and many samples for DNA analysis were collected and carried out to Japan.2.Field Research in 1996. January 6-February 3,1996. Area : Chitwan National Park, Central Nepal. Route : Kathmandu-Sauraha (Head Quarter of National Park)-inside of National Park-Kathmandu (15days).Collection : about 2350 sheets of herbarium specimens, 201 wood samples, 201 bark samples, 130 samples of sheeds, flowers, 60 samples of root and rhizomes and 19 samples for DNA analysis were collected and carried out to Japan.The herbarium specimens had been identified in major part and were distributed in some international herbaria and research institutes of botany including Tohoku University, University of Tokyo and National Herbarium, Department of Plant Research, Nepal. Collected wood and bark samples have been sectioned and analyzed.

本研究的目的是分析喜马拉雅地区树木的木材结构和其他形态特征如何随着海拔的升高而变化。为此，在本项目期间进行了两项实地调查，在这些实地调查期间，采集植物标本并干燥为标本，使用锯子、凿子和锤子从直立的树木上切下小块木材和树皮及其凭证标本。1.1994年的实地调查。1994年6月1日至1994年9月10日。所在地区：芒特山Manaslu和Mt.尼泊尔中西部的安纳普尔纳地区。路线：加德满都-Trisuli Bazar-沿Burigandaki-环绕Ganeshu Himal-Larkya La(海拔4900米)-沿Dudhu Khora-沿Marsyanagdi Hhora-Thorung Pass(海拔5110米)-沿Kali Gandaki-Pokhara-加德满都(约45天)。收集：收集了约18,000张植物标本，约780个木材样本，约490个树皮样本和许多DNA分析样本，并在1996年进行了实地考察。1996年1月6日至2月3日。地区：尼泊尔中部的奇特旺国家公园。路线：加德满都-Sauraha(国家公园总部)-国家公园-加德满都(15天)。收集：采集约2350张标本馆标本，201个木材标本库标本，201个树皮标本库标本库标本，130个草本植物标本，花卉标本库，60个根茎和根茎标本库标本，19个DNA分析标本库。标本库标本的大部分已经鉴定，并被分发到一些国际植物标本库和植物学研究所，包括东北大学，东京大学和尼泊尔国家标本馆，植物研究部。采集的木材和树皮样本已经进行了切片和分析。
