摘要
为了揭示不同微地形烟叶特色,通过随机区组试验,研究云贵高原山区坝地、坡地和台地3种微地形烟叶的品质特征差异.结果表明:1)坡地烟叶的香气类型为"中偏清",坝地和台地为"中间"香型;主体香韵坡地烟叶表现为"显著"和"较显著",而坝地和台地烟叶为"较显著"和"尚显著",坡地烟叶的辅助香韵除了"木香"、"辛香"外,还有"果香"成分.2)中部叶评吸总分各微地形处理间差异有统计学意义.3)中部烟叶致香物质质量分数由大到小为坡地烟叶,坝地烟叶,台地烟叶,坡地烟叶和坝地烟叶分别比台地烟叶高出46.56%和16.97%;烤后烟叶含梗率由大到小为坝地烟叶,台地烟叶,坡地烟叶.4)生育期烟叶蔗糖质量分数呈波浪形曲线,在旺长期时质量分数达到最大值,此时由大到小为台地烟叶,坡地烟叶,坝地烟叶;生育期和烤后烟叶氯素质量分数由大到小均表现为坡地烟叶,坝地烟叶,台地烟叶,上部烟叶和下部烟叶各处理差异有统计学意义(p<0.05),而中部烟叶差异有统计学意义p<0.01.坡地烟叶感官质量较好、致香物质和氯素质量分数较高、含梗率较低、蔗糖质量分数总体较高,因此其品质特征较优,坝地烟叶次之,台地烟叶最差.该研究结果为西南烟区不同微地形优质烟叶的生产及卷烟工业的品质需求提供理论参考.
In order to provide a theoretical reference for tobacco-producing regions in different micro-topog- raphies about tobacco quality production and quality requirements of the cigarette industry, a randomized block experiment was conducted, in which the characteristics of tobacco leaves planted in 3 kinds of micro- topographies （dam, sloping fields and platform） on the Yunnan-G＇uizhou Plateau were studied. The results showed that the aroma type for sloping tobacco was ＂middle but partial fragrance＂, and that of dam tobac- co and platform tobacco was ＂middle flavor＂. The main aroma for sloping tobacco was ＂significant＂ and ＂more significant＂, while that of dam tobacco and platform tobacco was ＂more significant＂ and ＂yet signif- icant＂, and auxiliary aroma included ＂fruit＂ component in addition to ＂woody＂ and ＂spicy＂ for sloping to- bacco. Difference of smoking total scores was highly significant between middle leaves under different mi- cro-topographies. The content of aroma substances for middle leaves was in the order of sloping tobacco~ dam tobacco〉platform tobacco; slope tobacco and dam tobacco was 46.56M and 16.97%, respectively, higher than platform tobacco for content of aroma substances. Stalk ratio of flue-cured tobacco appeared in the sequence of dam tobacco？platform tobacco〉sloping tobacco. Sucrose content of tobacco leaf showed a wave-shaped curve and achieved the maximum in the period of vigorous growth, and its trend was platform tobacco〉sloping tobacco^dam tobacco, which rose in the mature period. Chlorine content of tobacco dur- ing the growth periods and after curing was. sloping tobacco〉dam tobacco〉platform tobacco, and signif- icant difference was found in the upper and lower tobacco leaves for different micro-topographies, but highly significant for middle tobacco l＇eaves. Sloping tobacco had better quality characteristics than dam to- bacco because of its better smoking quality, higher aroma compounds and chlorine content, and high su- crose content, while quality characteristics of the platform tobacco was the poorist.
