摘要:
本研究以NC 71与对照品种K 326和NC 89在南北烟区9个省(市)的10个种植试点的烟叶样品为试材,在外观质量、常规化学成分、常规烟气成分、感官质量、主要致香成分五个方面进行了分析比较,结果表明NC 71在外观质量上与南北烟区对照品种K 326和NC 89相当,部分NC 71样品身份或油分稍好于对比品种;未检测出碱糖、碱氮、钾氯比值都较协调或是都不协调的样品,部分NC 71样品钾氯或碱糖和钾氯比值较协调。南方烟区湖南永州的NC 71样品碱糖和碱氮比值不协调;NC 71在焦油、一氧化碳和烟碱含量上总体高于照比品种;南北烟区种植试点的NC 71样品综合感官质量表现较好;北方烟区三种植试点NC 71致香物质总量优于NC 89,南方种植试点NC 71与K 326在致香物质含量上各有优势。

Research on Leaf Sample Quality in Introduced Flue-cured Cultivar NC 71

Abstract:
NC 71 and CK cultivar leaf samples from south and north tobacco planting-regions of China, were used to comparatively analyze in appearance quality, general chemical-composition, general flue-gas composition, sensory quality and major aroma components. The results indicated that there were no apparent differences between NC 71 and CK cultivar leaf samples in appearance quality; no leaf samples were observed with the harmonious or disharmonious ratios of sugar/nicotine, nitrogen/nicotine and potassium/chlorine, and partial leaf samples exhibited harmonious ratio of potassium/chlorine or ratios of sugar/nicotine and potassium/chlorine. Disharmonious ratios of sugar/nicotine and nitrogen/nicotine were observed in leaf samples from Yongzhou, Hunan, a south tobacco planting-region. Totally, in comparison with CK cultivars, relatively high TPM, nicotine, NFDPM and CO content were detected in NC 71 leaf samples. Compared to the CK cultivars, NC 71 leaf samples showed higher sensory-quality; High aroma content were detected in NC 71 leaf samples from Juxian, Shandong and Mudanjiang, Heilongjiang, and leaf samples from south tobacco planting-regions, exhibited their own advantages in aroma content.
