摘　　要：[目的]探讨墨西哥大叶种香草兰产量构成因素之间的变化规律,以明确其高产主攻目标。[方法]对墨西哥香草兰单株产量构成因素:花序数、每花序成花数、授粉成功率、保荚率(落荚率)和单荚重(百条豆荚重)进行相关分析和通径分析。[结果]花序数、每花序成花数对产量的影响较大,且均达到显著性水平;其他因子的影响相对较小。[结论]该研究为香草兰的稳产栽培提供了参考。[Objective] The aim was to study the relationship among component traits of yield per plant of Vanilla fragrans so as to clarify its high-yield principal target.[Method] Component traits of yield per plant of Vanilla fragrans like the number of inflorescences,flowers per inflorescence,pollination efficiency,retention rate（pod-falling rate）and the weight per bean（weight per 100 beans）were made correlation analysis and path analysis.[Result] The number of inflorescences and flowers per inflorescence had relatively larger effects on yield per plant,which both reached significance level,while the other factors had relatively less effects on it.[Conclusion] The research provides reference for the stable yield cultivation of Vanilla fragrans.
