Potted poplar ramets showed increased concentrations and rates of synthesis of phenolic compounds within 52 hours of having 7 percent of their leaf area removed by tearing, as did undamaged plants sharing the same enclosure. Damaged sugar maple seedlings responded in a manner similar to that of the damaged poplars. Nearby undamaged maples had increased levels of phenolics and hydrolyzable and condensed tannin within 36 hours, but exhibited no change in rates of synthesis. An airborne cue originating in damaged tissues may stimulate biochemical changes in neighboring plants that could influence the feeding and growth of phytophagous insects.
通过撕裂去除7%叶面积的盆栽杨树分株，以及共享同一围栏的未受损植株，在52小时内酚类化合物的浓度和合成速率均有所增加。受损的糖枫幼苗的反应与受损杨树相似。附近未受损的枫树在36小时内酚类物质、可水解单宁和缩合单宁的含量增加，但合成速率没有变化。受损组织产生的空气传播信号可能会刺激邻近植物发生生化变化，进而影响植食性昆虫的取食和生长。
