伤流是指从受伤或折断的植物组织伤口处溢出液体的现象,伤流液是由根压引起而流出的无色微酸性透明液体[1]。大多数植物都有伤流液,不同植物的伤流程度不同,同一类型的植物因品种不同,其伤流量不同[2];同一植物在不同季节中因根系生理活动的强弱、根系有效吸收面积大小等因素的影响,也会导致其伤流量有所差异。通过分析伤流液的数量、成分及各成分的含量,可以判断植物根系活动能力强弱,研究植物伤流液的抑菌、抗氧化活性等,具有重要的理论价值和应用前景。根据近年来有关植物伤流液的国内外研究报道,本文主要从收集方法、
Injury refers to the phenomenon of spilled liquid from the injured or broken plant tissue wound, which is caused by the root pressure and flows out of the colorless and slightly acidic transparent liquid [1]. Most plants have fluid injury, different levels of injury of different plants, the same type of plants due to different species, the injury flow is different; the same plant in different seasons due to the physiological activity of the root system, root effective absorption The size of the area and other factors, will also lead to differences in their injuries. It is of great theoretical value and application prospect to analyze the capacity of plant root activity and study the bacteriostasis and antioxidant activity of plant fluid by analyzing the quantity, composition and content of the fluid in the wound fluid. According to the reports of plant injury fluid in recent years at home and abroad, this paper mainly from the collection methods,
