| 中文摘要: |
| 以烤烟品种云烟87 为材料，分别在山东费县和湖南桂阳，通过大田试验研究2 种植物生长调
节剂对烤烟中上部烟叶农艺性状、经济性状及烟叶品质的影响。结果表明，喷施植物生长调节剂，对烟株
生长发育及烤烟中上部烟叶品质均有显著促进作用。其中植物生长调节剂6-BA 比茉莉酸+GA 在改善中
上部烟叶的农艺性状和经济性状上表现稍好，促进了烟株的生长和叶片的拓展，产量、产值、均价、上等
烟及上中等烟比例上均有显著提高，桂阳点上等烟比例提高了21.03%。茉莉酸+GA 在外观质量上表现较
佳，化学成分上更趋于协调，感官质量上两种植物生长调节剂在两地的表现不完全一致，但在香气质、香
气量、余味及评吸总分均高于对照。总体来看，茉莉酸+GA 对烤烟中上部烟叶品质的影响优于6-BA，茉
莉酸+GA 促进了中上部叶的生长发育，提高了烤烟中上部烟叶产量和质量，改善了烟叶整体品质。 |
| 英文摘要: |
| Using Yunyan 87 as materials，field experiments were conducted in Feixian of Shandong Province
and Guiyang of Hunan Province，to study the effects of two plant growth regulators on agronomic traits，economic
traits and quality of flue-cured tobacco. The results showed that，two plant growth regulators had a certain role
in promoting the quality of middle and upper tobacco leaves. Tobacco treated by 6-BA showed better agronomic
and economic traits in middle and upper leaves，while jasmonic acid + GA was better on the appearance quality，
chemical composition and sensory quality of middle and upper leaves of flue-cured tobacco. As a whole，the effect
of jasmonic acid + GA on quality of middle and upper leaves of flue-cured tobacco was better than that of 6-BA.
Meanwhile，jasmonic acid + GA promoted the growth and development of middle and upper leaves，improved the
yield，quality of middle and upper leaves，and the overall quality of flue-cured tobacco. |
