[ Objective ] The paper was to study the rooting promotion activity of plant extracts, so as to lay the foundation for development of natural source of roo- fing reagent with high efficiency, safety and environment friendship. [Method] Using mung bean rooting method, the rooting promotion effects of 33 plant extracts on mung bean section were studied. [Result] When the concentration was 1 mg/mL, Eupatorium adenophorum （stem and leaf）, Cryptomeriafortunei （stem and leaf）, Pinus yunnanensis （stem）, Pinus yunnanensis （leaf）, Rhododendron simsii （leaf）, Pinus armandii （leaf）, Litchi chinensis （pericarp）, P/nus armandiifruit （fruit） and Alnus cremastogyne （leaf） showed strong promotion effect on rooting of mung bean sections, and the rooting promotion rate reached over 100% ; the roo- ting promotion effect ofE. adenophorum （stem and leaf） was the strongest, reaching（1068.42 ＋7.87）%, which was extremely higher than the extracts of other plants. [Conclusion] E. adenophorum （stem and leaf）, C. fortunei （stem and leaf）, P. yunnanens/s （stem）, P. yurmanens/s （leaf）, R. simsii （leaf）, P. armandii （leaf）, L. chinensis （pericarp）, P. armandiifruit （fruit） and A. cremastogyne （leaf） all contained substances with st/ong rooting promotion effect, which could be further used for development of natural rooting reagent.
