Summary:This article was to understand allelopathy of gaseous volatiles of Eupatorium adenophorum stems and leaves on seed germination and seedling growth of Pinus yunnanensis. Pinus yunnanensis seeds were treated by fresh stems and leaves of Eupatorium adenophorum in translucent airtight container wider high concentration, middle concentration and lower concentration, respectively. Gaseous volatiles affected seed germination process; with the increasing processing concentration, the day on which seeds began to germinate and the day reaching germination peak were delayed, and the germination quantity on the day reaching germination peak was decreased; the day on which the germination quantity began to significantly reduce was delayed; the process curve was developed from sudden increase and sudden decrease to gentle change, and nearly became a beeline at high concentration. This article provides reference for scientific management of Pirus yunnanensis forests.
