US-Nepal Cooperative Research: The Role of Water Relations in Controlling the Leaf Life Cycle of Himalayan Trees

9731118 Zobel描述：该奖项是为美国-尼泊尔合作研究：水关系在控制喜马拉雅树叶生命周期中的作用。 研究人员是来自俄勒冈州州立大学科瓦利斯分校的唐纳德·佐贝尔和普拉莫德·K.尼泊尔加德满都特里布万大学的Jha将解决有关喜马拉雅树种的植物生物学基本问题。 的主要目标是- 1）确定的作用，水的关系，在管理叶的发展和叶衰老的树木在喜马拉雅山中部，和2）研究可能的机制，喜马拉雅树产生足够的膨压，扩大叶在旱季。 范围：该项目将是尼泊尔水资源关系研究的一个重大推动力。 除了培训年轻的尼泊尔科学家和提供必要的设备，在特里布万大学进行植物学研究，该项目将发展一个重要的区域联系，在Kumaun大学植物学家，印度谁与美国PI在同一主题上合作。 虽然印度和尼泊尔的团体都对喜马拉雅山的生态做出了重大贡献，但在努力和专业知识方面却很少协调。 对于美国科学来说，该项目将产生大量目前无法获得的关于喜马拉雅森林中水关系，植被和生态系统过程的数据，并将改善生物圈规模的分析和预测。 ***

9731118 Zobel Description: This award is for the US-Nepal Collaborative Research: The Role of Water Relations in Controlling the Leaf Life Cycle of Himalayan Trees. The investigators, Donald Zobel of Oregon State University, Corvallis, OR and Pramod K. Jha of Tribhuvan University, Kathmandu, Nepal will address fundamental questions in plant biology concerning Himalayan tree species. The primary goals are-- 1) to determine the role of water relations in governing leaf development and leaf senescence of trees in the central Himalaya, and 2) examine possible mechanisms by which Himalayan trees generate sufficient turgor to expand leaves during the dry season. Scope: This project will be a major boost for water relations research in Nepal. In addition to training of young Nepalese scientists and providing essential equipment to conduct botany research at Tribhuvan University, this project will develop an important regional link with botanists at Kumaun University, India who have collaborated with the US PI on the same topic. While both Indian and Nepalese groups have made substantial contributions to Himalayan ecology, there has been little coordination of effort and expertise. For US science, this project will produce a large volume of currently unavailable data on water relations, vegetation, and ecosystem processes in Himalayan forests and will improve analysis and prediction at the scale of the biosphere. ***
