Study on Altitudinal Variation of Wood Structure in Himalaya

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是如何随着海拔高度的升高而变化的。为此，在本项目期间进行了两次野外调查，在这些野外调查中，植物标本被收集并干燥为植物标本馆标本，用锯、凿和锤从直立的树木上切下小立方体的木材和树皮，并带有它们的凭证植物标本馆标本。1994年6月1日至9月10日。地区：Mt. Manaslu和Mt.尼泊尔中西部安纳普尔纳地区。路线：加德满都-特里斯里巴扎尔-沿布里甘达基-环绕甘内舒喜马拉雅山-拉尔基亚拉（海拔4900米）-沿着Dudhu Khora-沿着Marsyanagdi Hhora-Thorung山口（海拔5110米）-沿着Kali Gandaki-Pokhara-加德满都（约45天）。约一万八千张植物标本，约七百八十个木材样本，1996年采集了490多个树皮样品和大量DNA分析样品，并将其运往日本。1996年1月6日至2月3日。地区：奇旺国家公园，尼泊尔中部。路线：加德满都-索拉哈（国家公园总部）-国家公园内-加德满都（15天）。约2350张植物标本，201个木材样本，201个树皮样本，130个草类，花卉样本，采集了60份根和根茎标本和19份DNA分析标本，并带往日本，其中大部分标本已鉴定，分布于国际植物标本馆和东北大学、东京大学、尼泊尔植物研究部国家植物标本馆等植物学研究机构。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.
