摘　　要：[目的]调查研究六盘山地区野生伏毛铁棒锤（Aconitum flavum Hand.-Mazz.）的花器特性和开花结果习性。[方法]调查项目包括野生伏毛铁棒锤的花器形态以及抽序、开花、结果习性。[结果]伏毛铁棒锤为顶生总状无限花序,白天、黑夜、阴雨天小花均可开放,序花期5~18 d,朵花期5~7 d;雌雄同株受粉,存在异花受粉情况,座果率较高（86.4%）,但自然繁殖率很低。[结论]该研究可为伏毛铁棒锤的人工驯化栽培提供理论依据。[Objective] The research aimed to survey and study characteristics of flower organs and flowering and flowering and fruiting habits of wild A.flavum Hand.-Mazz.in Liupanshan Area.[Method] The surveying items were the characteristics of flower organs,anthotaxy,flowering,bearing of the wild A.flavum Hand.-Mazz..[Result] The results indicate that A.flavum Hand.-Mazz.is general boundless inflorescence.The flowerlet can open whether in day and night or cloudy and rainy.The florescence of it is usually 5-18 days and flowerlet is usually 5-7 days.The wild A.flavum Hand.-Mazz.is geitonogamy,but it being xenogamy once in a while.Its fruited rate is very high,but the natural reproduction rate is very low.[Conclusion] The study provides a theory basis for domestication and cultivation of A.flavum Hand.-Mazz.
