Abstract: The relationship between the physical properties and regular chemical compositions and appearance quality were explored by simple correlation analysis, path analysis, and variance analysis of 125 samples of flue-cured tobacco. The results showed that the leaf thickness and leaf weight had the closest relationship (r = 0.808 ). There were very significantly negative correlation between leaf thickness, leaf weight, total potassium, sugar/alkali, nitrogen/alkali, and K/Cl, which all had significant correlation with potassium. On the other hand, there are significantly positive correlation between mass burning rate and total potassium, sugar/alkali, nitrogen/alkali, and K/Cl. Also there were very significantly negative correlation between equilibrium moisture content and filling power, but the relationship between tensile strength and chemical composition of tobacco was not significant. For the physical indices, leaf weight had the most important influence on the appearance quality of tobacco leaves, and had significant influence on leaf color, figure, and chrome, but little effect on maturity, leaf structure, and oil content

煙葉的物理特性主要包括葉片厚度、葉質(zhì)重、含梗率、填充性、拉力、平衡含水率、燃燒性等,是煙葉質(zhì)量的重要組成部分,直接影響著卷煙制造過程中的產(chǎn)品風(fēng)格、生產(chǎn)成本及其他經(jīng)濟(jì)因素。2003年以前煙葉物理特性并沒有引起大家足夠的重視,直至尹啟生等[1]、劉國順[2]對全國煙草質(zhì)量及國內(nèi)外煙葉質(zhì)量進(jìn)行差距分析以及中國煙葉公司發(fā)布的白皮書中發(fā)現(xiàn)中國煙葉質(zhì)量與津巴布韋和巴西煙葉尚存在一定差異之后[3],逐漸成為近年來煙葉質(zhì)量評價(jià)的重要研究內(nèi)容。
煙葉化學(xué)成分是決定物理特性的內(nèi)在因素,物理特性則是煙葉化學(xué)成分的外在表現(xiàn)。近幾年,有關(guān)煙葉物理特性與化學(xué)成分的關(guān)系已有報(bào)道[4-17],然而這些大都局限于個(gè)別產(chǎn)區(qū)或個(gè)別指標(biāo)之間的研究,很少有人進(jìn)行全面系統(tǒng)的分析,外觀質(zhì)量與物理特性間的定量研究更是少見。
本研究較全面系統(tǒng)地測定了烤煙各等級的主要物理指標(biāo)和常規(guī)化學(xué)成分,并對其進(jìn)行了外觀質(zhì)量鑒定,通過對這些指標(biāo)進(jìn)行簡單相關(guān)分析、通徑分析及方差分析,探索了它們之間的關(guān)系,以期為進(jìn)一步研究烤煙物理指標(biāo)與化學(xué)成分及外觀質(zhì)量間的關(guān)系,評價(jià)煙葉質(zhì)量提供參考依據(jù)。
