盆栽白杨Euramericana]分株在52小时内表现出增加的酚类化合物的浓度和合成速率，其7%的叶面积通过撕裂而被移除，与共享相同围栏的未受损植物一样。受损的糖枫[糖槭]幼苗的反应方式类似于受损的杨树。附近未受损的枫树增加了酚类化合物和水解和缩合单宁在36小时内，但没有表现出任何变化的合成率。来自受损组织的空气传播的线索可能会刺激邻近植物的生化变化，从而影响植食性昆虫的摄食和生长。
Potted poplar [Populus .times. euramericana] ramets showed increased concentrations and rates of synthesis of phenolic compounds within 52 h of having 7% of their leaf area removed by tearing, as did undamaged plants sharing the same enclosure. Damaged sugar maple [Acer saccharum] seedlings responded in a manner similar to that of the damaged poplars. Nearby undamaged maples had increased levels of phenolics and hydrolyzable and condensed tannins within 36 h, 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.
