摘要
为筛选能为科研、生产和育种利用的优异烟草种质资源。对来源于国内外的141份烤烟、18份白肋烟和6份雪茄烟的烟叶常规化学成分和主要生物碱进行检测、比较和聚类分析。结果表明:总糖和还原糖含量以烤烟最高,总氮、烟碱和氧化钾以白肋烟种质最高。总植物碱和烟碱含量以烤烟种质自来黄2243最高,雪茄烟种质Dutch(Ohio)最低;降烟碱和烟碱转化率以烤烟种质平板柳叶最高,以烤烟种质二性子和白肋烟种质Burley11B最低。聚类分析将165份种质分成4类,烤烟种质主要集中在第1和第4类,其主要特征是总糖和还原糖含量较高,烟碱转化率较低;第2类的总糖和还原糖含量低,总氮、总植物碱和氧化钾含量高;第3类的烟碱和总植物碱含量低,降烟碱含量高,烟碱转化率高。不同类型种质资源的化学成分和生物碱差异明显,筛选出的不同梯度烟碱的种质可为烟碱的进一步研究提供材料支撑。
The study was aimed to screen out the excellent tobacco germplasm resources which could be used in the field of scientific research,production and breeding.Conventional chemical composition and major alkaloids were tested,compared and clustered for 141 flue-cured tobacco,18 burly tobacco and 6 cigar germplasm resources from China and abroad.Total sugar and reducing sugar contents were high in flue-cured tobacco germplasms,while total nitrogen,nicotine and potassium oxide were high in burley tobacco germplasms.Total alkaloid and nicotine content were the highest in flue-cured tobacco germplasm Zilaihuang 2243,and the content of cigar germplasm Dutch(ohio)was the lowest.The nicotine and nicotine conversion rates were the highest in the tobacco germplasm Pingbanliu,and those for tobacco germplasm Erxingzi and Burley11B was the lowest.The 165 accessions were divided into 4 groups for clustering analysis.Flue-cured tobacco germplasms were mainly concentrated in Group 1 and 4,characterized by high total and reducing sugar content and low nicotinic conversion rate.Group 2 was low in total and reducing sugars,and high in total nitrogen,total alkaloids and potassium oxide.Group 3 had low nicotinoids and total alkaloids,high nicotinic reduction,and high nicotinic conversion rate.The chemical composition and alkaloids of different germplasm resources have significant difference.The selected germplasms with different gradients could provide useful material for further study of nicotine.
