Name: Wedelia chinensis (Osbeck.) Merr., belonging to the Compositae plant Wedelia trilobata, and perennial. Compositae (Composite) invasive weeds, environmental adaptability, fast breeding. The stem segments of plasticity, cutting, layering and soilless culture experiments show that as long as a section of the stem segment with have successful development expand the population of potential [2].With different plant growth substances, including 6-BA, ethephon and salicylic acid and sucrose as reagents, reagent the configuration, acquisition School of Wedelia chinensis as experimental material, effect of 6-BA, ethephon and salicylic acid and sucrose four growth substances on fresh cut flowers and storage of Wedelia chinensis. The experimental results show that: four kinds of solution treated cuttings, by contrast, sucrose on fresh cut flowers and storage of Wedelia chinensis is the worst, 6-BA, ethephon on fresh cut flowers and storage of Wedelia chinensis and salicylic acid on fresh cut flowers and storage of Wedelia chinensis best.Keywords:growth substances; 6-BA; ethephon; salicylic acid; sucrose; Wedelia chinensis; cut flower preservation前言三裂蟛蜞菊（W edelia trilobata L.），又名南美蟛蜞菊，地锦花，穿地龙，为菊科蟛蜞菊属植物。原产于中国，越南，柬埔寨，缅甸等热带地区。在我国主要分布于华南和台湾地区，该植物具有超强的繁殖能力，主要通过与土壤接触的节间与匍匐茎蔓延的方式繁殖，能够通过化感作用抑制其他植物的生长而发展成单优种群。植物生长物质调节植物的生长发育，也影响植物的成花生理和花周期。本实验用0mg/
