白肋烟不同类型转化株烟碱转化率的叶位间和叶点间变异
Variation of nicotine conversion rate among different leaf positions and leaf areas for burley tobacco of different conversion type
摘要
Abstract
GC method was used to analyze the nicotine conversion rate of burley samples from different leaf positions and leaf areas of plants with different conversion levels. The results showed that for non-converters and high converters, the distribution of nicotine conversion rate among different leaf positions and leaf areas was consistent with small variation; nicotine conversion rates for all the samples were below 2% for non-converters and were above 85% for high converters, with no chimera charac-teristics; so the sampling position had no impacts on identification results. For low converters and medium converters, great variation of nicotine conversion rate existed among different leaf positions and leaf areas, and the chimera characteristics were displayed. The range of nicotine conversion rate for low converters was 2.5%～4.8% for leaf positions, and 2.6%～7.0% for leaf areas. The range of nicotine conversion rate for medium converters was 2.51%～90.6 % for leaf positions, and 2.7% ～66.9 % for leaf areas. Since the nicotine conversion rate of certain leaf samples were below the current converter standard, the sampling position would have great impact on converter identification, so lowering the standard was quite necessary for more efficient screening.关键词
