[Objective] The basis of the development of new type of natural rooting agent with high-efficiency,safety and environment friendship was laid through the research on the rooting activity of the extract.[Method] The promotion of the extracts from 33 plants to the rooting activity of green bean stem-cutting was tested.[Results] At the treatment of 1 mg/ml,Phaseolus radiate.the extracts from 9 plants: Eupatorium adenophorum(stem and leaf),Cryptomeria fortunei(stem and leaf),Pinus yunnanensis(stem),Pinus yunnanensis(leaf),Rhododendron simsii(leaf),Pinus armandii(leaf),Litchi chinensis(pericarp),Pinus armandii(fruit) and Alnus cremastogyne(leaf) had strong promotion to rooting and the rooting rates of all were over 100%.The extract from Eupatorium adenophorum(stem and leaf) showed the strongest bioactivity of rooting promotion.[Conclusion] The 9 plants contained the intensively active material in rooting promotion,which could be developed as natural rooting agent.
