| 为了解不同移栽期对福建烟叶感官评吸质量的影响，以翠碧1 号、红花大金元、云烟85、云烟
87 等品种或品系为材料，通过3 年9 个地点的不同移栽期试验，采用主成分分析和相关分析的方法，分析
不同移栽期处理下7 个气温指标与感官评吸质量的关系，探讨影响烟叶品质的关键气温因子。结果表明，
随着移栽期的提前，烟叶感官评吸得分升高，烟叶质量呈变好的趋势，主要表现为烟叶香型由浓香逐步向
清香转变，烟叶甜感由焦甜逐步向清甜转变，烟叶香气质变好，香气量更足，杂气变轻，烟气变细腻，刺激
性变小，余味变好。主成分分析结果表明，7 个气温指标存在着较多的信息重叠，可以转化为用3 个主成分
表示，这3 个主成分的累积方差贡献率达到90.535%，能基本反映不同移栽期烟草生育期气温因子的变异
信息。相关分析结果表明，中部烟叶感官评吸得分与第二主成分得分呈显著负相关，与第一主成分得分、第
三主成分得分的相关性均不显著。综合以上分析表明，提早移栽可以彰显福建烟叶的清香型风格特色，提
升烟叶的品质。 |

| In order to research the effects of transplanting date on sensory quality of tobacco leaves，and the
key air temperature factors affecting the quality of tobacco leaves，9 transplanting date experiments of tobacco from
2011 to 2013 were conducted based on varieties or lines materials such as Cuibi-1，Yunyan-85，Yunyan-87，
Honghuadajinyuan，etc.，and the relationship between tobacco leaves taste quality and temperature factors was
discussed by statistical analysis method. The results indicated that the full-bodied flavor and baking-sweet flavor of
flue-cured tobacco leaves faded down，the fen-flavor and fen-sweet intensified，the aroma quality smelled better，
the aroma quantity become more plentiful，the offensive odor smelled lighter，the smoking become more exquisite，
the irritation decreased，and the remaining taste tasted better with the transplanting date moving up in the local.
The results of principal component analysis showed that there was a lot of information overlap in the 7 temperature
indexes，which could be transformed into a representation by 3 principal components. The cumulative variance contribution of the three principal components reached to 90.535%，which showed that the 3 principal components
could stand for the variation information of the 7 temperature factors. The results of correlation analysis showed that
the correlation between sensory taste score and the second principal component score was negatively significant，but it
was not significant between the sensory taste score and the first or third principal component score. All these indicated
that the fen-flavor characteristics of Fujian tobacco leaves highlighted and the quality of tobacco leaves improved with
the transplanting date moving up in the local. |
