【摘要】 【目的】探究烯效唑和二甲戊灵复配对马铃薯种薯发芽及生理影响,确定马铃薯种薯抑芽剂烯效唑和二甲戊灵最适复配配比。【方法】将烯效唑和二甲戊灵按照有效成分不同比例进行复配,得到8个不同配比浓度处理,以清水为对照,测定了马铃薯种薯经浸种后储藏期间的抑芽效果,以及各处理芽长、发芽率、失重率、还原糖含量和过氧化物酶（POD）活性。【结果】复配药剂对马铃薯种薯具有明显的抑芽作用,当马铃薯储藏60 d时,清水对照组A₀B₀还原糖含量最大,达到51.0087 mg/g,与其他处理差异极显著（P<0.01）;当储藏75 d时,清水对照处理组马铃薯种薯过氧化物酶活性降到最低,为3.7133(0.01A₄₇₀·min^-1),与A₂B₀、A₃B₁处理组差异极显著（P<0.01）;当A₀B₀组马铃薯储藏90 d时,马铃薯失重率和发芽率均达到最高,分别为21.01%和96.13%,与所有药剂处理组的差异极显著（P<0.01）;当A₀B₀组马铃薯储藏90 d时马铃薯芽长最长,为23.06 mm,与所有药剂处理差异极显著（P<0.01）。【结论】A₃B₁（二甲戊灵330 mg/L+烯效唑25 mg/L）处理浓度配比对马铃薯种薯有较强抑芽作用,可进一步制剂研究。更多还原

【Abstract】 【Objective】The present paper aimed to explore the effects of mixture of uniconazole and pendimethalin on the germination and physiological effects of potato seed potatoes, and to determine its suitable ratio acting as potato seed potato inhibitors.【Method】According to the different ratios of active ingredient of uniconazole and pendimethalin, eight treatments with different concentration concentrations were obtained using water as a control.The sprout inhibition effect of the mixture on the potato seed and the bud length, germination rate, weight loss rate, and reducing sugar content were also measured during storage stage.【Result】The mixture had a significant sprout inhibition effect on potato seed.When the potatoes were stored for 60 days, the treatment A₀B₀ had the highest reducing sugar content, reaching 51.0087 mg/g, and was extremely significant with other treatments（P<0.01）; when stored for 75 days, the peroxidase activity of potato seed in the A₀B₀ was decreased to a minimum of 3.7133(0.01 A₄₇₀·min^-1), which was extremely different from those of the A₂B₀ and A₃B₁ treatments.When the potato seed was stored for 90 days, the weight loss rate and germination rate of A₀B₀ treatment reached the highest, being 21.01% and 96.13%, respectively, and were extremely significant with other treatments（P<0.01）.When the potato seeds were stored for 90 days, the longest potato sprout length of A₀B₀ reached 23.06 mm and was extremely different with other treatments（P<0.01）.【Conclusion】The mixture A₃B₁（dimethalin 330 mg/L plus uniconazole 25 mg/L） was selected as the appropriate mixture of uniconazole and pendimethalin.更多还原
