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

9731118佐贝尔描述：该奖项授予美国-尼泊尔合作研究：水关系在控制喜马拉雅树木叶片生命周期中的作用。研究人员，俄勒冈州立大学的Donald Zobel和尼泊尔加德满都Tribhuvan大学的Pramod K.Jha将解决与喜马拉雅树种有关的植物生物学的基本问题。主要目标是：1)确定水分关系在控制喜马拉雅中部树木叶片发育和叶片衰老中的作用；2)研究喜马拉雅树木在旱季产生足够的膨胀力以扩展叶片的可能机制。范围：该项目将对尼泊尔的水关系研究起到重大推动作用。除了培训年轻的尼泊尔科学家并提供必要的设备在Tribhuvan大学进行植物学研究外，该项目还将与印度库曼大学的植物学家建立重要的地区联系，后者已与美国PI在同一主题上进行了合作。虽然印度和尼泊尔的团体都为喜马拉雅生态做出了重大贡献，但几乎没有协调努力和专业知识。对于美国科学来说，这个项目将产生大量目前无法获得的喜马拉雅森林水关系、植被和生态系统过程的数据，并将改进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. ***
