Airborne signals of communication in sagebrush: a pharmacological approach.

摘要: When plants receive volatiles from a damaged plant, the receivers become more resistant to herbivory. This phenomenon has been reported in many plant species and called plant-plant communication. Lab experiments have suggested that several compounds may be functioning as airborne signals. The objective of this study is identify potential signals used communication between sagebrush (Artemisia tridentata) individuals field. We collected one branch each 99 individual plants. Eighteen different were detected by GC-MS analysis. Among these, 4 compounds; 1.8-cineol, β-caryophyllene, α-pinene borneol, investigated under natural conditions. branches which received either 1,8-cineol or β-caryophyllene tended get less damage than controls. These results should considered further possible candidates for generalized sagebrush.
