[ 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 rooting 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 adenopkorum (stem and leaf) , Cryptomeria fortunei (stem and leaf) , Pinus yunnanensis (stem) , Pinus yunnanensis (leaf) , Rhododendron simsii (leaf) , Pinus armandii (leaf) , Ltichi chinensis (pericarp) , Pinus 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 rooting promotion effect of E. 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. yunnanensis (stem) , P. yunnanensis (leaf) , R. simsii (leaf) , P. armandii (leaf), L. chinensis (pericarp), P. armandiifruit (fruit) and A. cremastogyne (leaf) all contained substances with strong rooting [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 rooting reagent with high efficiency, safety and environment friendship.
