摘　　要：木质部空穴化和栓塞能降低植物的水输导能力,从而影响其抗旱性。本文综述了木质部空穴化和栓塞形成、修复的过程和机理,并对研究该过程的方法进行了简单介绍。这不仅对了解植物的水分运输过程,而且对选育抗旱植物、指导节水灌溉具有重要意义。Xylem cavitation and embolization could reduce the water conductivity of plants and then affect their drought resistance.In this paper,the forming and refilling process and mechanism of xylem cavitation and embolization were summarized and the research methods were introduced simply.It was important not only for understanding the water conducting process in plant but also for drought-resistant plant breeding and water-saving irrigation.

关 键 词：木质部 空穴化 栓塞 修复
