摘要
2009年以烤烟主栽品种NC89为试验材料,研究中上部叶片性状间的相关性、叶长、单叶重的感官评吸质量及其与生物碱含量的关系。研究结果表明,除中部叶质重与叶长呈负相关,外其他中上部叶片性状均与叶长呈正相关。中上部叶长适宜范围分别为56～68cm、53～65cm,且叶长每增加3cm烟碱含量分别增加2.80mg/g、1.67mg/g;中部叶单叶重在8～16g范围内,平均每增加2g烟碱含量增加2.2mg/g;上部叶单叶重在9～21g范围内,平均每增加3g烟碱含量增加1.60mg/g。降烟碱、假木贼碱、新烟草碱与烟碱的变化趋势一致,且中上部烟叶的生物碱含量随叶片长度、单叶重的变化趋势一致。中、上部叶片长度分别在53.01～68.99cm、59.01～65.99cm,单叶重分别在14.001～16.999g、15.001～18.999g范围内感官质量较好。
The experiments were set up with NC89,the leading variety in middle Henan,2009 to investigate the middle leaves length and the weight of per leaf of individual alkaloids and smoking quality and the relationship of leaf traits.Results showed that there existed positive correlation with leaf length and other leaf characters of middle and upper leaf except weight per area and leaf length of middle leaves had negative correlation.The appropriate ranges of middle and upper leaves length were 56-68 cm and 55-65 cm and with the length increased 3 cm the nicotine contents increased 2.80 mg/g and 1.67 mg/g.With the weight per leaf increased 2 g,the nicotine content increased 2.2 mg/g in the range of 8-16 g of middle leaves and with the weight per leaf increased 3 g,the nicotine contents increased 1.60 mg/gin the range of 9-21 g of upper leaves.Nicotine,nornicotine,anatabine and anabasine had the same change with the different leaf traits and the alkaloids content of middle and upper leaves had the same changes with the leaves length and weight per leaf change.The appropriate ranges of middle and upper leaves length were 53.01-68.99 cm and 59.01-65.99 cm,weight per leaf were 14.001-16.999 g and 15.001-18.999 g had the better smoking quality.
