摘要
采用统计分析方法,以河南省许昌市为例,对豫中地区2003-2012年烤烟品种NC89的C3F初烤烟叶样品主要化学成分含量变化进行了测试分析。结果表明,NC89的化学成分含量在不同年份间存在广泛的变异,总糖、还原糖、淀粉、蛋白质、烟碱、总氮、钾、氯含量及糖碱比、氮碱比、钾氯比达到了极显著差异,两糖比差异不显著。12个化学成分指标中,钾氯比、糖碱比的变异较大,总氮含量、氮碱比和两糖比的变异较小。两糖比稳定,糖碱比较低,氮碱比低于1,但钾含量偏低,钾氯比不协调。
The variation of chemical components content of C3 F flue-cured tobacco samples of NC89 between 2003 to 2012 in Xuchang city of Henan province was statistically analyzed. The results showed that there were significant differences between contents of total sugar, reducing sugar, starch, protein, nicotine, potassium, chlorine, the ratio of total sugar to nicotine and the ratio of total nitrogen to nicotine among different years while no significant difference in the content of the ratio of reducing sugar to total sugar. The variation coefficients of total nitrogen, the ratio of total nitrogen to nicotine and reducing sugar to total sugar were small. The variation coefficients of total nitrogen, the ratio of potassium to chlorine and the ratio of total sugar to nicotine were high. Overall, the ratio of reducing sugar to total sugar was stable; the content of potassium and the ratio of total sugar to nicotine was low; and the ratio of total nitrogen to nicotine was smaller than 1; but the potassium content was low and ratio of potassium to chlorine was uncoordinated from NC89.
