摘要
木本植物木质部空穴和栓塞化现象的发现至今已近80年历史，国外学者对此做了较多的研究，国内此方面的研究极少。木质部空穴和栓塞化研究是木本植物体内水分传输研究的前沿所在，不同学者在不同地区对不同材料的研究结果各异，争议颇多。本文对这一研究方向近年来的资料作了概括和总结，包括栓塞化现象的发现、检测方法、诱因及形成机理、木质部栓塞化同输水结构间的关系等方面。
The studies of cavitation and embolization are the advanced subject of xylemwater transport problerns in woody plants. There have been published many papers, butdifferent viewpoints exist among different scholars. Based on the last 80 year' studies aroundthe world, the literature about xylem cavitation and embolization is summarized anddiscussed in this paper, which include the parts of the discovery, measuring methods,induced factors, formation mechanism, the relationship between hydraulic architecture andxylem embolism, etc. The hot position of this field is also pointed in order to draw moreinterests in the study.
