POWRE: Integration of Ecophysiology and Wood Science Through Research and Site Visits

Gartner 98-70480 该项目描述了旨在提高PI通过研究和参观实验室整合生态生理学和木材科学研究的能力的休假年活动。 资助的工作涉及在温室中对万年青橡树幼苗（Quercus ilex）的研究，询问木材如何同时满足运输水和提供机械支持的需求。 PI预计，从垂直方向以高角度生长的幼苗将使用更多的茎用于专门的机械支撑，因此可用于水运输的横截面较少。 PI将测量幼苗的机械，水力和生长特性，然后调查其木材解剖。 如果有其他资金，PI将补充这项研究，对该领域中较老树木的不同角度的树枝进行研究，PI将访问其他科学家正在研究树木和木材的实验室。 现场访问将帮助PI将研究置于背景中，并增加PI对欧洲这些研究领域的了解。 进一步了解木材在活树中的功能将有助于PI了解干旱适应，并将使PI对我们的森林操作如何影响森林产品的木材质量具有更大的预测能力。

Gartner 98-70480 This project describes sabbatical-year activities designed to increase the PI's ability to integrate research in Ecophysiology and wood science through research and visits to labs. The funded work involves research on evergreen oak seedlings (Quercus ilex) in a glasshouse, asking how wood accommodates the simultaneous needs to transport water and to provide mechanical support. The PI expects that seedlings grown at high angels from vertical will use more of their stem for specialized mechanical support, and thus will have less cross-section available for water transport. The PI will measure mechanical, hydraulic, and growth characteristics of the seedlings, followed by investigating their wood anatomy. If other funds are available, the PI will supplement this research with a study of branches at different angles on older trees in the field, and PI will visit laboratories where other scientists are working with trees and wood. The site visits will help the PI put research in context and increase the PI's knowledge of these research areas in Europe. Further understanding of how wood functions in living trees will help the PIs understand drought adaptations, and will give the PIs more predictive power on how our forest manipulations will affect wood quality for forest products.
