摘　　要：目的:以川产地道药材附子为材料,研究喷施烯效唑对其原植物植株形态及总生物碱含量的影响,为附子高产栽培措施的制定提供新的理论依据。方法:在附子生长过程中的两个重要时期喷施不同浓度烯效唑,观测不同处理下植株主要形态特征并测定子根中总生物碱含量。结果:附子原植物经烯效唑处理后,表现出株高降低,叶面积减小,茎粗、叶片数、须根数、干物质量增加等变化;子根中总生物碱含量较对照有所增加或降低,但与对照差异不显著。结论:烯效唑对附子总生物碱含量无显著影响,从调整植株形态的角度考虑以子根形成期喷施效果更好,增产作用以子根膨大期效果更佳,均以120 mg/L效果最显著。Objective：To study the effects of spraying uniconazole on plant morphology and total alkaloid content of Aconitum carmichaeli for providing theory base for establishment of planting measure.Methods：The mainly morphological character and total alkaloid content of Radix Aconiti Lateralis Praeparata were studied under different uniconazole spraying time and density.Results：Unieonazole could decrease plant height and leaf area,increase stem diameter,leaves and fibril roots,and the amount of dry matter.The difference in total alkaloid was not significant.Conclusion：In this experiment,Spraying uniconazole has no significant effect on total alkaloid content of Aconitum carmichaeli.It is better for increasing yield per plant to applied 120 mg/L unieonazole at sub-root enlargement stage than sub-root formation stage,and it is better to applied the same density at another stage for adjusting the plant morphology.
