摘要
通过控制旺长后期土壤水分含量,以研究干旱胁迫对白肋烟中烟碱向降烟碱转化的影响。结果表明,在晾制过程中,不同程度干旱处理导致B37高转化株烟碱转化率的变化存在差异,随烟叶着生叶位的升高烟碱转化率快速增长阶段向后延迟,B37非转化株烟碱转化率整体均维持在较低水平,处理间差异不明显;轻度干旱有利于降低高转化株的降烟碱含量和烟叶(包括转化株与非转化株)的烟碱转化率,提高非转化株烟碱转化性状的稳定性。
Effect of drought stress on burley tobacco＇ s nicotine conversion was studied by controlling soil water content in fast growing period . Results showed that nicotine conversion in B37 converters was changing dissimilarly in different drought stress treatment, and the fast increasing phase of the percent of nicotine conversion （PNC） delayed when the leaf position ascended in air-curing stage. Nicotine conversion in B37＇ s non-converters maintained at lower level and there was no distinct difference in all treatments. Moderate drought may help to decrease converter＇s nomicotine content and tobacco leaves＇ （containing con- verter and non-converter） nicotine conversion, and hence increase the stability of nicotine conversion of non-converters.
