摘要
为明确烤烟柔软度与烟叶外观质量的关系,利用柔软度仪检测了江西省480份烤烟样品柔软度,并评定了外观质量。相关分析结果表明:烟叶柔软度与颜色、油分、色度呈极显著正相关,与成熟度、叶片结构、身份、总分呈极显著负相关。建立回归方程:Y=53.201-5.578X_3+2.852X_6+2.136X_5(叶片结构X3、油分X5、色度X6),R^2为0.818,具有良好的拟合度。通径分析表明:叶片结构、色度、油分对烟叶柔软度的影响较大。江西烟叶柔软度有一定差异,并且与烟叶外观质量各指标关系密切,这为以烟叶柔软度作为烟叶外观质量评价指标之一、精细评价烟叶质量提供可能性。
In order to determine the relationship between softness and appearance quality of flue-cured tobacco,the softness of 480 flue-cured tobacco samples in Jiangxi Province were detected by softness instrument,and the appearance quality was evaluated. The results of relationship analysis showed that the softness of tobacco was extremely significantly positively correlated with color,oil and chroma,and extremely significantly negatively correlated with maturity,leaf structure,identity and total score. The regression equation Y =53. 201-5. 578X_3＋ 2. 852X_6＋ 2. 136X_5（ leaf structure X_3,oil X_5,chroma X_6） was set up with R^2as0. 818,and it had good fitting degree. The path analysis results showed that leaf structure,chroma and oil had comparatively large effects on tobacco softness. In conclusion,the softness of tobacco in Jiangxi had certain differences,and was closely related to each index of appearance quality. The results provided the possibility to carefully evaluate tobacco quality with softness as one of the evaluation indexes of appearance quality.
