| 摘 要： | 以烤烟云烟97为材料,采用田间试验研究了成熟期不同淹水时间处理对烤烟石油醚提取物、主要化学成分及致香物质含量的影响。结果表明,在不同淹水处理后,烤烟中部叶石油醚提取物、总糖、还原糖、烟碱、钾、氯含量以及钾/氯低于对照,而总氮和氮/碱高于对照;其中总糖、烟碱含量降幅达到44.06%和48.52%,总氮含量升幅达到47.64%。大多数致香物质含量和致香物质总量及不同种类致香物质含量都有不同程度的降低,致香物质中以新植二烯降幅最大达到52.15%,4种致香物质种类中以苯丙氨酸类和类西柏烷类致香物质下降最为明显,分别达到34.75%和31.90%。在各淹水处理中,以淹水5d对烤烟烟叶品质影响最大,说明成熟期淹水时间越长,对烟叶品质形成越不利。 |

| Abstract: | A field experiment of the flue-cured tobacco cv.Yunyan 97 at the maturity was conducted to research the influence of different flooded periods on the content of petroleum ether extract,the main chemical constituents and aroma matter.Results indicated that,for the middle leaves of flooded flue-cured tobacco,after different waterlogging phases,the contents of petroleum ether extracts,total sugar,reducing sugar,nicotine,potassium,chlorine and the ratio of potassium to chlorine were lower than the control.Moreover,the content of total nitrogen and nitrogen alkali ratio were higher than the control;the amplitude reduction of total sugar and nicotine was 44.06% and 48.52%,respectively,and the increase amplitude of total nitrogen was 47.64%.For most of aroma components,their content,total content and each kind content were declined at different degrees,the neophytadiene with the biggest decline of 52.15%,the phenylalanine group and cembratriendiol group with the most significant dicline of 34.75% and 31.90% among four kinds of flavor matter,respectively.During all the flooded treatments,the first 5 days was the most influential period for the quality of flue-cured tobacco leaves,which showed the worse their quality was the longer the flooding time was. |
