白肋烟不同程度烟碱转化株后代烟碱转化率株间变异研究
Study on variation of nicotine conversion rate for offsprings of burley tobacco with different conversion rates
摘要
Abstract
Early conversion stimulation method was used to analyze alkaloid composition and content in tobacco leaves of Dasuo 26 and their selfing populations in order to verify reliability and validity. Results showed that the selfing populations of plants with percent nicotine conversion ( PNC) lower than 2. 5% was stable and all had PNC lower than 2. 5% , indicating that the parent plants were non-converter. The three selfing generations from parent plants with PNC between 2. 5%-and 3% showed significant segregation of the trait of nicotine conversion within the range of 0. 439%-10. 331% , 0. 466%-21. 834, and 0. 394%-3. 757% , respectively, which indicated that the parents were converters. The selfing populations from parent plants with PNC greater than 3% showed great variation for nicotine conversion, and the 2 selfing lines from parents with PNC greater than 50% had the highest conversion level, indicating that the parents were high converters. Therefore, PNC greater than 2. 5% can be a reliable standard to determine a converter plant.关键词
