降水与烤烟感官评吸质量的关系

对山东22个植烟县169个乡镇的2001年、2002年和2004年共计464个烤烟初烤烟叶C3F样品的评吸指标得分与同期5～8月降水进行了相关和逐步回归分析，结果表明，(1) 降水与烟叶评吸质量的相关和逐步回归分析结果基本一致；（2）香气质、余味、杂气、刺激性、燃烧性、总得分与降水的回归方程达极显著水平，劲头和灰色与降水的回归方程达显著水平，浓度和香气量与降水量在0.05显著水平下没有得到逐步回归方程。（3）评吸总得分与5月和8月降水量呈正相关；燃烧性与5月和8月降水量呈负相关；劲头与6月降水量，呈正相关；香气质与5月降水量呈负相关，与6月降水量呈正相关；余味和杂气与5月和5～8月降水量呈正相关；刺激性与5～8月总降水量呈正相关。

Relationship between Precipitation and Sensory Quality of Flue-cured Tobacco Leaves in Shandong

Correlation and stepwise selection regression analysis were used to investigate the relationships between sensory quality and precipitation in tobacco growing areas of Shandong Province. The two approaches produced very similar result. The difference of stepwise selection regression equations for aroma quality, after taste, offensive taste, irritancy, combustibility and total score with precipitation were significant at 1% level. There was significance difference in stepwise selection regression equations for impact and ash with precipitation. No variable met the 0.05 significance level for entry into the stepwise selection regression equations for taste concentration and volume of aroma with precipitation. The total score of sensory quality were positively related to precipitation of May and August, whereas the type of aroma and combustibility were negatively related. There were positive correlations between impact of tobacco leaves and precipitation of June. The quality of aroma were negatively related to precipitation of May, yet positively related to June. The after taste and score of offensive taste were positively related to precipitation of May and total precipitation from May to August. There were positive correlations between the score of irritancy and total precipitation from May to August.
