以中抗倒伏甜荞品种宁荞1号为材料，设置0、100、200和300 mg kg–1烯效唑干拌种处理，研究倒伏习性、产量、茎秆抗折力、倒伏指数、茎秆形态特性和茎秆解剖结构的变化，探讨烯效唑干拌种对甜荞茎秆抗倒性能的影响。结果表明，烯效唑干拌种对甜荞茎秆抗倒性能有显著影响。随烯效唑干拌种浓度的增加，产量、茎秆抗折力、第2节间粗、第2节间干重、节间充实度、机械组织层数、机械组织厚度、茎壁厚度、维管束数目和维管束面积先增加后降低，倒伏率、倒伏指数、株高、茎秆重心高度、茎秆鲜重和第2节间长先降低后增加。当烯效唑干拌种浓度为200 mg kg–1时，能有效优化甜荞茎秆结构，改善茎秆质量，减小倒伏风险，增加产量。

Lodging is one of the important factors affecting the yield and quality of common buckwheat (Fagopyrum esculentum M.) worldwide. Ningqiao 1, a cultivar of common buckwheat with moderate lodging resistance was used in this study to investi-gate the dynamic changes of lodging behavior, yield, culm snapping resistance, lodging index, culm morphological characteristics and culm anatomical structure seed dressing with uniconazole powder (0, 100, 200, and 300 mg kg–1). The results indicated that seed dressing with uniconazole powder had significantly effects on the lodging resistance of culm in common buckwheat. With the increase of uniconazole powder concentration, the yield, culm snapping resistance, diameter of the 2nd internode, dry weight of the 2nd internode, filling degree, mechanical tissue layer number, mechanical tissue thickness, culm wall thickness, vascular bundle number, and vascular bundle area showed an increased-decreased trend, whereas, the lodging percentage, lodging index, plant height, culm gravity height, culm fresh weight, and length of the 2nd internode showed an decreased-increased trend. In this case, the treatment of seed dressing with 200 mg kg–1 uniconazole powder could optimize the culm structure, improve the culm quality, reduce the lodging risk, and enhance the yield of common buckwheat.
