摘要: 對(duì)山東22個(gè)植煙縣169個(gè)鄉(xiāng)鎮(zhèn)的2001年,、2002年和2004年共計(jì)464個(gè)烤煙初烤煙葉C3F樣品的評(píng)吸指標(biāo)得分與同期5～8月降水進(jìn)行了相關(guān)和逐步回歸分析,，結(jié)果表明，(1) 降水與煙葉評(píng)吸質(zhì)量的相關(guān)和逐步回歸分析結(jié)果基本一致,；（2）香氣質(zhì),、余味、雜氣,、刺激性,、燃燒性、總得分與降水的回歸方程達(dá)極顯著水平,，勁頭和灰色與降水的回歸方程達(dá)顯著水平,，濃度和香氣量與降水量在0.05顯著水平下沒有得到逐步回歸方程。（3）評(píng)吸總得分與5月和8月降水量呈正相關(guān),；燃燒性與5月和8月降水量呈負(fù)相關(guān),；勁頭與6月降水量，呈正相關(guān),；香氣質(zhì)與5月降水量呈負(fù)相關(guān),，與6月降水量呈正相關(guān)；余味和雜氣與5月和5～8月降水量呈正相關(guān),；刺激性與5～8月總降水量呈正相關(guān),。Abstract: 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.
