Study on Altitudinal Variation of Wood Structure in Himalaya

本研究项目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是如何随海拔高度的变化而变化的。为此，本项目期间进行了两次实地考察，在实地考察中，收集植物标本并将其干燥为植物标本馆标本，用锯子、凿子和锤子从直立的树上砍下小立方体的木材和树皮，并将其作为植物标本馆标本。1994年实地调研。1994年6月1日—1994年9月10日。地区：马纳斯鲁山和安纳普尔纳山地区，尼泊尔中西部。路线：加德满都- trisuli bazaar -沿burigandaki -绕甘尼许山脉- larkya La。沿着Dudhu khora - Marsyanagdi Hhora-Thorung山口（海拔5110米）-沿着Kali gandaki - pokhara -加德满都（约45天）。收集：共收集到日本植物标本馆标本约18000张，木材标本约780张，树皮标本约490张，DNA分析标本多份。1996年实地调研。1996年1月6日至2月3日。地点：尼泊尔中部奇旺国家公园。路线：加德满都- sauraha（国家公园总部）-加德满都国家公园内部（15天）。采集：共采集植物标本馆标本约2350份，木材标本201份，树皮标本201份，草、花标本130份，根、根茎标本60份，DNA分析标本19份，运往日本。植物标本室标本大部分已鉴定，分布于日本东京大学、日本东北大学、尼泊尔国立植物标本室等国际植物标本室和植物研究所。收集的木材和树皮样本已被切片和分析。

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.
