摘　　要：[Objective] The present experiment was conducted to study the effects of bamboo vinegar on seed germination and seedling growth of different flue-cured to- bacco varieties, so as to provide some references for its application in tobacco pro- duction. [Method] By using indoor culture dish method and greenhouse seedling- raising plate culture,four different concentrations of bamboo vinegar dilution （50, 100, 200 and 400 times）were designed and clean water was used as the control （CK）. The germination indices of Yunyan 97, Guiyan 2, Jiucaiping 2 and Bina 1 were de- termined after seed germinating. The seedling growth indices of Yunyan 97 were investigated after 10 days of spaying bamboo vinegar on seedling leaves at the 3r~ time. [Result] Compared with CK, different bamboo vinegar dilutions could inhibit the seed germination and seedling growth of all flue-cured tobacco varieties. The seed germination rate and index, vigor index, whole length, root length, stem length and fresh weight of seedlings of all varieties presented decreasing trend to varying de- grees, moreover, most of them reached significant level. Compared with CK, spray- ing different concentrations of bamboo vinegar dilution at the seedling stage could improve the quality of seedlings. In all bamboo vinegar treatments, the plant height, the maximum leaf length and root volume under 100 times dilution treatment were the highest with 3.36 and 10.14 cm, and 0.92 ml, respectively. And the stem girth, dry weight and the maximum leaf width of seedlings under 400 times dilution treat- ment also showed the highest with 1.82 cm, 0.262 g and 5.74 cm, respectively. [Conclusion] Supplying different concentrations of bamboo vinegar solution on culture dish could inhibit the seed germination and seedling growth of flue-cured tobacco, while spraying 100-400 times bamboo vinegar solution to leaves could promote the seedling growth and improve the quality of Yunyan 97 to varying degrees.[目的]研究竹醋液对不同品种烤烟种子萌发及幼苗生长的影响,为其在烟草生产上的应用提供参考。[方法]采用室内培养皿种子萌发试验和温室育苗方法,分别设50、100、200、400倍竹醋液稀释处理,以清水作为对照,测定云烟97、贵烟2号、韭菜坪2号和毕纳1号种子发芽和云烟97烟苗生长的相关指标。[结果]在萌发试验过程中,与对照相比,使用不同浓度竹醋液抑制了不同烤烟品种种子的萌发和生长,各烤烟品种的种子发芽率、发芽指数、活力指数、幼苗全长、根长、茎长、鲜重均呈现降低趋势,且部分达到显著水平。在幼苗期对云烟97叶面喷施不同浓度竹醋液,与对照相比,喷施不同浓度竹醋液可不同程度提高幼苗素质。其中在不同浓度竹醋液处理中,以100倍处理烟苗株高、最大叶长和根系体积最高,分别为3.36、10.14 cm和0.92 ml;以400倍处理的烟苗茎围、干物质重和最大叶宽最高,分别为1.82 cm、0.262 g和5.74 cm。[结论]在培育皿中添加不同浓度竹醋液会抑制烤烟种子的萌发和幼苗生长;在漂浮育苗过程中,对幼苗叶片喷施100～400倍竹醋液可在不同程度上促进幼苗生长并改善其质量。
