[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.展开更多
