中文摘要
木质部是陆地植物水流的主要组织,因此它是植物在其环境中生存能力的主要决定因素。木质部管道应最大限度地提高导电性,同时保护蒸腾流免受空气进入(空化),并保持水输送所需的负压。空化导致木质部导管的空气栓塞(堵塞)。其结果是水力传导性降低,进一步加剧了植物的水分胁迫。我们将通过实验来进一步了解水应力诱导空化的机理,以及生理因素、木材解剖结构和环境对空化的影响。
英文摘要
Xylem is the principal tissue for water flow in land plants and as such it is a primary determinant of a plant's ability to survive in its environment. Xylem conduits should maximize conductivity while protecting the transpiration stream from air entry (cavitation) and maintaining the negative pressures required for water transport. Cavitation leads to air embolism (blockage) of xylem conduits. The result is a reduction in hydraulic conductivity, further exacerbating plant water stress. We will conduct experiments designed to learn more about the mechanism of water-stress-induced cavitation and how air-seeding is influenced by physiological factors, wood anatomy and environment.
