[Objective] The aim was to explore tobacco varieties which satisfy tobacco formula and is suitable to be grown in ecotopes simultaneously. [Method] Interior and exterior qualities of tobacco were compared and identified based on agronomic and economic characters of tobacco in fields. [Result] Yunshai No.1 was better in both agronomic and economic characters. Specifically, the fragrance was dominated by empyreumatique and aroma; the highly-qualified variety is fragrant and sweet, with little irritation, which gives the tobacco smoke a light, mild flavor. As for Virgini- a934, economic characters were better, but agronomic characters were just ordinary. Similar to Yunshai No.l, dominated by empyreumatique and aroma, the variety was with distinctive resin and herbaceous fragrance. What's more, it tasted good with high quality and usability. Cunsanpi was ordinary in agronomic characters, and poor in economic characters, with coordinated quality and chemical composition. It is fra- grant and the smoke is clean. However, the quality was not so high and it tasted not so good. Tengruan No.2 was good in agronomic characters, but poor in eco- nomic characters, which gives delicate fragrance, but not clean enough. Waiweiba and Mijie Qinggeng neither taste well nor smell sweet, performing ordinary in agro- nomic and economic characters. Hence, the two varieties seem bad in quality and ranks poorly. [Conclusion] In terms of sensory quality, the varieties from high to low were Yunshai No.1, Virginia 934, Cunsanpi, Tengruan No.2, Waiweiba and Mijie Qinggeng. 展开更多

为筛选高烟碱、低总糖含量以及农艺性状优良的晒烟栽培种,用于除传统卷烟外的其他烟草制品(口含烟)的生产,从国家烟草种质资源库中选取88份晒烟种质,在山东沂水县按当地晒烟栽培调制技术进行生产,对烟株的农艺性状和烟叶烟碱、总糖含量... 为筛选高烟碱、低总糖含量以及农艺性状优良的晒烟栽培种,用于除传统卷烟外的其他烟草制品(口含烟)的生产,从国家烟草种质资源库中选取88份晒烟种质,在山东沂水县按当地晒烟栽培调制技术进行生产,对烟株的农艺性状和烟叶烟碱、总糖含量(质量分数)进行测定并进行聚类分析和灰色关联度分析。结果表明:依据晒烟烟叶的烟碱和总糖含量,在欧式距离为2.0时将88份晒烟种质分为三大类,第一类晒烟烟碱和总糖含量的适宜性最差,有5份种质;第二类晒烟烟碱和总糖含量的适宜性次之,共有32份种质;第三类晒烟的烟碱和总糖含量的适宜性最好,共有51份种质。通过对烟碱和总糖含量适宜性最好的晒烟农艺性状指标聚类分析,在欧式距离为1.7时又将第三类晒烟分为3类,第Ⅰ类晒烟种质(11份)的农艺性状表现最优,第Ⅱ类晒烟种质(28份)的农艺性状表现次之,第Ⅲ类晒烟种质(12份)的农艺性状表现最差。对第Ⅰ类晒烟种质(共11份)进行烟碱、总糖含量以及农艺性状的灰色关联度分析,加权关联度排序依次为S32>S65>S63>S58>S48> S61>S36>S47>S43>S59>S29。因此,筛选出的优质晒烟种质为S32,其次是S65和S63。 展开更多
